I remember you didn't fill the torque converter with fluid when you did the last rebuild. May have been the thing that caused early failure of the torque converter.
lsx Matt I'm a transmission rebuilder here in rochester ny he's right the case passages are the same just swap the linkage components valvebody,plate,wiring harness and also the 1-2 accumulator housing assembly and you should be good
I guess I got extremely lucky. I’m a diagnostic tech now but I’ve done everything over the years except for transmissions. I bought a camaro with a bad 4l60e and decided to rebuild it myself. It’s been going strong 6 years now. I used a lot of sonnax parts like the performance pack, pinless pistons, ceramic balls, transgo plate, and did some of the mods like the hole in the passage for using the overrun when not in overdrive. I really like the feel of the sonnax kit as it is tame unless you really get into the throttle.
Great video. In the real world at this point, a normal person should just bite the bullet and buy a new transmission or pay someone to rebuild it. Im looking forward to see if your Frankenstransmission will come to LIFE.
How about you do the outside wiring mods to run the 65. iirc you just have to wire the input speed sensor to the ecu. Then with HP tuners do a transmission segment swap for a 65 and it should be good. I helped a buddy do this swap. (I only did the tunning part). He did the install and the wiring. And as far as I recall, that was the only mod it needed. I think he may have gotten the pigtail from the donor truck. This was on a 01 tahoe.
Looks like you didn't replace the bushing in the 4l60e use a flat edge on the drum if you cant see light behind the edge scotch bright all the drums up
I took a closer look at it and its loose in the cage. The separator plate from the Tahoe’s trans is going back in so that shouldn’t be a factor as far as wear is concerned. A did an air test and the 3-4 seal is leaking on the 65e trans.
Did you buy that torque converter on eBay? If you did… I’ve purchased form eBay before and my trans burnt up. Root cause was the wrong clutch type in the torque converter.
Not a transmission question but do you have any videos recommendations, tips, or how-to videos on how to replace a blend door motor under the dash of a 2003 tahoe???
@@lsxmatt that's my recommendation for a future video. I have tried to get the old door motor out there but it's such a pain I can't even get a tool in there to get to the screws.
Is it a dual control where driver side has a temp slide and passenger has a temp slide? Let me guess it blows hot on driver side and cold on passenger side?
Downside to the 80 is that it takes much more horsepower to turn and the gearing is much higher, requiring a lower ring and pinion gear to equal the 4L60 in performance.
Yep, I can sympathize! My "new" 4L65E in my Camaro went in no problem and ran about 1/2 mile, then no gears. All my checks looked good.

Oh, and my trailblazer is on its 5th 4l60. 3 of them failed due to converter failure. There is a pwm valve that allows the tcc to slip. It wears the bore in the valve body and leaks causing chatter then failure. I thought the last one was going to set my truck on fire

Good luck with that. My truck has the 4L60E as well but mine is a 2010 so i have been debating putting a 6l80E in it once the 4l60E takes a dump. The kit is like $7000 but that also includes a built trans. I could put 3 4L60Es in it for that much but it would still be a 4L60E.
@@LS3438 The 4L80 will not bolt to my transfer case and does not have 6 gears. The 6L80E kit updates the trans to bolt up to my transfer case and has 6 gears.
HEY don’t use that pump in your core transmission for the one in tahiti. 2009+ 4l60e’s have different style stator tubes to accommodate for an input speed sensor on the input shaft. The only way it would work is if you use the input drum AND the pump out of your core. Keep the ISS plugged into the pump and just leave it unplugged in your tranny. Also, not sure on Tahiti’s transmission but the pump cover may not work with each other, some covers have an o-ring gasket around the edge, others have a wedge seal that sits in the case.
Let me know if you run into anything once you install. I build over 10 4l60e’s a week. We have to mix and match parts all the time. I talked to a guy earlier that said he had a unit come back after 20,000 miles kind of similar to what your setup is going to be. The problem was unrelated to the case/valve body/pump being switched around. So it seems to hold up. Cooler line fitting holes are a little bit different connecting to the case.
You need to tear that transmission completely apart. It's just a waste of time if something else is broken in their, and all that clutch material that has gone around inside of it needs to be cleaned out. The sensor in the pump is an ISS sensor. Input speed sensor. The reluctor on the input shaft is what the ISS reads. You need to be careful when mixing pumps and different input shafts.
Matt....I do not TRUST any builder....I do them myself...lots of info and advice out there to DIY that would be better than any Stage 1000 that builders offer A 4L80E should also be DIY built ....it has it own quirks that need to be fixed n modded
