- 04 SRT4 built by ND Performance with a 41TE 4 speed automatic transaxle. Short driving video demonstrating its proper operation.
This video is quite old, now, having been produced in mid-2016. I still get comments and emails on this car. It has long since been sold, and remains with the person who bought it.
Do I have another? Yes, is the short answer. I converted a 2005 Dodge Neon SE to an SRT4 back in 2006, and enjoyed it in many configurations over the years. As the need for a commuter car came up in early 2020, so I converted it, much like the car in this video. It has been a reliable daily driver ever since. That car will be featured in one of these videos, as it too, will be offered up for sale soon.
The conversion process will not be detailed by me any further than it has been in the comments, and what is below. Your best bet on building your own is to acquire a PT Cruiser turbo as a parts car. However, you will need to do some fabrication on the SRT4 intake manifold, and you will run into some tuning issues with the PCM. 2003 PTGT PCM is setup for a PWM cooling fan. You should use a 2004-05 PTGT PCM in any case, as it will not have some of the torque limitations inside of it. Otherwise, plan on getting tuning from Needless Torque, as Duster360 is aware of how to remove the limitations. You will need to run a second power wire to the PCM connector to power up the automatic side of the PCM. There are kits for the transmission, but as this platform has now aged, the best ones seem to be harder to find. Alto clutches with Kolene steels are getting hard to find. Sonnax valve body kits are a good idea, and you should get their differential pin retainer, if your differential is not already equipped. You will need a neon automatic left side mount, axle. Use a PTGT right side intermediate shaft and SRT4 right axle. You'll have to fabricate the cold side pipe. Wiring you need to read diagrams on.
This is a much better driving setup than people would guess, if done properly. I have more or less moved on from the 2.4L platform cars, and am not available to do a conversion for you, nor offer tuning, parts, etc. If you want one turnkey, be on the lookout for my white 2005 Neon, which will be offered up on SRT Forums and FB marketplace sometime in the near future.

When I first saw this I was shocked saying “no they ruined it” then they did a pull and my jaw dropped.
Well done. Very well done
Love this transmission swap. Simple, but different. I'd love to see it on a strip against a stock SRT4. Never gotta let go of the boost.
I have had lots of people ask me what is involved in this swap. There's a lot to it, and it is not for someone without at least some fabrication and electrical skills. Having said that, the formula is fairly straightforward. You'll need:
1. SRT4/PTGT engine w/SRT4 intake manifold
2. PT turbo transaxle w/torque converter, flex plate and starter
3. PT PCM (GT much preferred)
4. 03+ Neon Automatic left axle
5. 03+ Neon automatic transaxle mount
6. Transmission cooler (I got the largest generic one I could from the parts store)
7. Wiring (options include using the PT transmission wiring and splicing yourself, or sourcing and overlay from Kinnetic Kreations)
8. Several pieces of 2.5" aluminum tubing, silicone bends, etc for cold side pipe fabrication
9. Ton of small items like ATF+4, hardware, etc
10. Automatic shifter, cable, bracket, and brake pedal, if converting from a 5 speed
Bolting the transaxle in is the easy part. Get the shifter, cable and brake pedal done, if your car is a 5 speed. Get those mechanicals done first. Next, figure out how mount your cooler. I mounted mine to the AC condenser, and it fit just perfectly in the sheet metal cutout up front, but I did do some clearancing of the center core support. Intake manifold will need to be pie cut to rotate the throttle body up and away from the transaxle. Mine is almost parallel to the crankshaft. Will need to fabricate the cold side pipe, and it will be extremely tight. I cut a small amount off the intercooler, to move hose forward about 1 inch, which helped a lot. Have to get creative here. After that, wiring. Study the manuals, or buy the kit from Kinnetic. I highly recommend tuning on the PCM from a reputable tuner. For PTGT PCMs, you can use Diablo. For non-GT PCMs, I think the only current option is the Syked tuner.
Can Autostick work? If you're willing to do the wiring and the work needed to make the shifter work, then yes, but you'll have no Autostick display in the cluster.
FAQ:
Can you use the 40TE from a regular neon? Sure. It will blow up. Maybe not immediately, but it will, and for no net gain vice using the 41TE
Will I do this conversion for you? No. Your only chance on that is if I decide to sell the car I recently completed.
Do I know of any shops that will do this conversion? Not offhand, sorry.
How much power will the automatic take? No one is really sure, but there are several PTGTs in the 400whp running just fine.
Recommendations:
1. Rebuild your transaxle while it is out of the car
2. Install the available differential saver brackets, if yours is not already equipped
3. Install a shift kit (worth the
is this parts list the safe if I wanted to do this kind of build in a 1st gen neon?
@@katsyarissha4837 Not from me, unfortunately. This is a project best accomplished with a PTGT parts donor at the ready.
Wow that's amazing. Great video man 😎
I love the video! Very well done, sir! The fuel for my ambition to start a future project!
Thanks for the kind words! I have since built another, and am using it as a daily driver. I will get a video of it one of these days
Absolutely! Love the content brotha! Keep it up!
Love it, I miss my neon.
Ultra drive FTW. This is actually a very good pairing when you get the right converter. I recently tuned a build that went 9.50’s running one of these; it was an aluminum rod 2.4 on a Gen 2 PTE 6466 peaking 37-38 #’s in a 98 RT chassis. Race weight was around 2300lbs and the thing rolled out HARD. This car was running a really right converter from Sonnax and the 60’ was amazing.
any resources on this build?
You seemed to be a bit nervous on second count...3 seconds later I discovered why :D
Lots of opinions few facts. Indeed it accelerates more quickly at the expense of top end speed.
Were you able to use the pt gt half shaft to have equal length axles? I'm in the process of getting everything I need to do the conversion. I have a complete running 03 pt gt with a mopar stage 1 pcm injectors and the mopar bov plate. The insurance company totaled out and I bought back from them. I'm just trying to figure out how to use the equal length axles on a 2003 dodge neon sxt any info you may have on this would greatly be appreciated. I am disabled and can no longer drive a standard.
This is awesome and sounds exactly like my 06 pt gt H.O! I can hear 2 different whistle sounds from your turbo, is this normal? I only ask because since I removed my stock airbox, mine makes the same whistle as yours.
Outstanding.
Are there any modifications need for this auto trans?
How many neons do you have?!?!? And what rims? Beauty.
how much did it run you to convert it?
how long did this swap take and whats the cost? i wanna do this manuals in traffic is a pain.
these cars are Rare everyone has the srt8's i would like to do an Awd swap too.
i wonder if you can swap it from the caliber R/T awd, but thats a freaking CVT smh.
pretty unique!!!
I just picked up one for my twin daughters' and would like to convert to an auto. Is there a way to get your email address to talk about this conversion?
I love it.
Assuming you still have the car or remember the build, did you happen to have a Greddy Type FV blow off valve by chance? Your car (other than mine) is the only one I've heard that makes that high boost whistle/whine at WOT.
No. All stock as far as that goes. Whine is more a function of the intake plumbing. Most setups manage to cut that whine out
How much was the Conversation?
I did build a second one of these cars, and it had refinements from lessons learned on the last car, namely in the area of tuning. I sold that car recently, and you may see a white 2005 SRT-4 automatic running around the Mobile, AL area. With that, I am no longer tuning or building any 2.4L platform cars. For future SRT-4 automatic builds, I recommend @duster360 from Needless Torque Calibrations (www.needlesstorque.com/) to cover tuning you may need. Most other information you need is covered in the comments in this thread. I will try to periodically answer questions as they come in, but I am not accepting work to convert your car, nor do I offer kits, parts or tuning for these anymore.
Did the auto slow it down? I'm sitting in my stock srt4 right now and it pulls way harder than that it seems
Maybe it's the reduction in tq?? Still quick as crap! So my question becomes, was this a PTGT pcm tuned up? I know they come down tuned from the get go so maybe the tune brings it close to stock SRT4?
No reduction in torque, no reduction in HP. It is a PTGT PCM tuned with a Diablosport i2.
i would love to own this car wow
Sweet!!
I like this idea. I would never do it to my srt4. But the way I see things the car shifts with no need to drop The acceleration so you lose no boost ever. That's a plus. I know some people can shift with out getting off the gas. But iv also seen people blow an engine that way. So pros and cons just like everything else. But again. Good job.
ki11m3please325 I've seen trans tear themselves to shit well because we have weak transmission.
perfect
Very nice indeed. Could I utilize a pt gt auto along with the pt s pcm to install into my srt?
Yes, exactly.
I think u should make more videos on it
Could I use the transmission from my pt cruiser touring (turbo). If I’m not mistaken the touring (turbo) and the gt are mostly the same.
They are exactly the same. In fact all turbo engines and transaxles are the same across the various trim levels in the PT's. The difference is only in the PCM programming.
Wow man how many SRTs do you own ? Im trying to buy one right now in south FL not going well
At the time of the video, I had 7. Down to one, now.
what transmission did y'all use and what else had to be swapped out?
41TE. Left side mount (2.0 / 40TE neon), mods to intake, starter, flexplate, fabricated cold side pipe, wiring, more.
Is there anyway you can do a video showing the steps (pointing, not doing the build) and how it all looks from underneath and such
This would be difficult to do, given how tight everything is. I did make a post describing some of what needs to happen.
@@funtdrv please! Im very interested in doing this just for a daily
wow great! its from a PT GT? is it beefed out?
It is running on a PTGT PCM.
41te trans? Did you build it at all? Shift kit or stock?
The car in this video used a stock trans. I have built another car, and added a shift kit, and other parts for increased reliability.
What all was needed to do the swap. and how did the pcm wire compared to the srt4.
It's a PTGT PCM. Lots of little wiring differences, but not impossible, obviously.
How do you take over the issue of never getting in boost on 4th gear? I have the PT GT and its a huge NO.... Never boost on 4th gear
My current SRT4 auto swap make 16-18psi in 4th gear. The trans has a few mods to it, but nothing major.
I have the Same exact plan. How much did you invest in this swap?
It can be done cheap, or it can be done right. Right is going to cost more, but cost will depend on what parts you are starting with.
I’m trying too put a 2.4t in my 2005 neon auto sxt which is a 40te but can be made into a 41te by installing the clutch drumb, I’ll need too modify the intake , intercooler intake, harness too make it all work correct?
Think there's quite a bit more to it than just that to turn it into a 41TE. The 41TE case is physically larger, uses a larger torque converter with a different bolt pattern. Your best bet is to find a PT turbo as a complete donor car.
@@funtdrv how long would the 40te last with stock boost
If you come to Middletown, NJ with this, I might be interested in buying it!!
This car sold years ago
@@funtdrv Oh okay! Thanks 4 letting me know!
interesting, but hey, were you missing the pcv hose?
It's definitely there. Look closely.
I'm about to do something similar but my neon is a 03 SE automatic with the 2.0 and I'm swapping the motor for a 2.4 out of a PT GT,i was considering a trans swap too but the donor car is also automatic and my automatic is completely rebuilt case and all with only 10k on it so it just seems like a waste to pull it
Except that the trans in the PT gt is a heavier unit, and will actually survive behind that engine. Your stock 40te will have issues, only a matter of time.
So i should plan on the trans swap too then,i was told that it would hold up fine and that mine was lower geared as well. ?
what fucking traffic
Can you help with some instructions in things to note when doing this. I have a manual transmission that i am hoping to swap with my old automatic transmission
What did you get automatic transmission out of
It is a 41TE from a PT GT.
Did you do this conversion on you own or a shop? Im a paraplegic and want to get an srt but obviously cant shift gears
We have a small shop here, and did the conversion in house. It is far from a bolt in affair, but also far from impossible, either. Despite negative comments, there are many cases where an automatic in an SRT4 makes perfect sense.
@@funtdrv I have a question was the PT GT pcm basically plug and play if not what did you have to do to get it to work. I have a PT touring that I would like to be able to tune without going standalone just yet. She makes about 240 maybe a little more N/A with pretty much a fully built motor.
@@TechImpossible Is yours turbo? There are options to tune those. I used an 03 PTGT PCM and tuned with Diablosport. The non-GT PCMs have fewer tuning options, but there are ways.
@@funtdrv Sadly mine is not turbo. I'll tell you what I want to do. Basically I plan on doing mostly safety this year roll cage, 5 point seats etc. Also this year I'm gonna be installing my new transmission which is a 31th that does not use the transmission TCM. This cause my car to rev limit to 3500rpm I believe haven't installed the transmission yet so idk if this is the case. That's one thing also I would like to increase factory 3 step you could say from 6250rpm to something like 7200rpm. Also would like to be able to turn a bit for afr because I have a fully built head with stage 2 cams so I would like to maximize power to be made there. I may have left out some info I'm writing this from my phone but if you think any more info would help just ask. Also wanted to say sweet swap always like when people do the impossible.
Also what'd to add I know I dont have a turbo but could I still use a pt gt pcm or would it not compensate for that. If not guess turbo is added to the list this year too.😁
Hey if you were to sell one of your automatic srt 4 neons how much would you sell it for?
I really don't know, TBH. I would sell the one I have now, but I actually enjoy commuting in it :) This one has a Turbobay BWS, a host of other minor bolt ons (stock long block), KW V2 coilovers, BBS wheels, Wilwood BBK, and a lot more. However, it is a neon swap car, and has a branded title (hit a deer when it was only 3 weeks old). I bought it from the friend who owned it originally, and then swapped various SRT4-based drivelines into it. Was always my project car. I have been driving it daily for almost 15 years, now.
@@funtdrv Are you possibly selling it. I would love an automatic one because my parents wont let me have a manual dodge neon srt 4
@@devonhieshmon6305 I wouldn't rule it out, but I hadn't been planning on selling it.
What radiator is being used?
Stock with the largest external transmission cooler you can fit.
Did you have to do any modifications to the wiring harness?
Lots. It is a hybrid wiring harness between srt4 and PTGT.
@@funtdrv would it be better to use the harness from the ptgt ? Thanks for getting back to me . Really wanna do this swap but not sure what I might run into .
@@luisrosas4769 you'll have no choice but to make a hybrid harness. No way around it. You'll need parts from both. Only other option is to shell out the bucks for a nice one from Kinnetic. Look them up.
@@funtdrv how do I go about making a hybrid harness any tips on what I need to cut or add ?
@@luisrosas4769 You'll need to study the wiring diagrams for both cars and see what the differences are. You'll be looking in particular at all the changes for the transmission. Alternatively, you can probably buy a turn key harness from Kinnetic.
I'll stick with my row it myself 5 speed srt4 ;)
how many dodge neon do you have
At the time of this video, 7. I own two, now.
I didn't heard any popcorn sad day for an SRT
So is is a regular neon trans?
PT Turbo (41TE). Stock neon (40TE) will not hold up.
What transmission wanting to swap mines out to automatic
41TE
Good job. I may do that to my son's one of these days. The 604 with a good converter is plenty stout for this application. Easier on the rest of the drive train, too. After you've been driving for many years, shifting gets old. I have to chuckle when some youngsters are totally turned off by an automatic, like it's going to make their penis shrink if they aren't shifting every few seconds.
What would your son say to that?
I was one of those guys 10 years ago. Now im looking up auto swaps for my srt4 lol
0 to 100 real quick
I commend the work but why would you do this?
Here’s a guess. He wanted an srt4 but an automatic
@@typedrew 😂
Can I do his myself?
There's nothing magical about it, but you will need to have, or be able to get people with skills in mechanical, electrical and fabrication. Electrical can no be handled via an overlay wiring harness from Kinnetic, but nothing gets around the need to cut and weld the intake manifold and to build all of the necessary piping.
Do you still have this?
No. I believe it lives in southern AZ, now. However, building another one soon, as a daily driver.
@@funtdrv by the way your talking I know you used to drive freightliners.
any way I can get your email I have a few questions I have a project neon my self
How could I contact you?
I built a second one of these automatic cars, and drove it for the past three years. I sold that car recently, and am now completely out of the SRT-4 game. I will try to respond to questions as I can, but I think it is best for the questions and comments to be public, so that other people can find answers out publicly.
2020 update?? Yes no?
I sold this car about 3 years ago. However, I converted another car as a daily driver. Many more mods to that car, but have not had any time to make a video of it.
What ECU do you run to do that swap?
Pt cruiser gt pcm
@@kellicofer9353 Thank you!
Do you have any social media accounts for contact?
No, sorry.
@@funtdrv How much would you say is to build one ? I had a SXT I was planning to drop a Auto PTGT into but life took a turn of events.
@@TruChaosTV very difficult to say. No two situations are the same, and no two people's abilities are the same. If you had a complete PTGT and a full shop available, you might be able to do it yourself for not much more than the purchase price of the donor car. If you had to pay a shop for it all, then it could exceed the value of a SRT4 several times over.
Would you like to sell it?
The car in this video was sold years ago. I built another one and it is my daily driver. I wasn't planning on selling it, but everything has its price
What bov
Stock
Autos rule.. srt 4 in a pt cruiser
Why
DumMYLiTCloUtGod69 because they wanted it dumbass
No.
Wtf
Why get a srt4 and make it auto? It's just slower now
Nope
Ewwww 👎🏽👎🏽
