I’m going to turn one done and I can put the exact dimensions when I’m done if that helps. I have the sprag and a sonnax out race ordered. So when it comes in.

@@naudydave yes it will help a ton thank you

@@davesperformance88 so I’m not sure on what race. I use the stock one for 4l80 and use a 34 element sprag. I haven’t used the pro mod one yet. When I do I’ll see what is all need to piece one together if possible.

@@naudydave I did a lot of research and it looks like you would need a 4t80 forward outer race.

@@davesperformance88 I’m kinda confused on what we’re working on. Th400. So they have a pro mod drum that’s 36 element sprag and uses like c4 clutches or something. It takes like 5 of them. You also can use a smooth th400 drum and machine the outer step.040 down and run a 34 element sprag and 4l80 direct drum outer race and use 4l80 clutch pack and pressure plate and get 4 clutches. You can always get a hold of me at naudydave@gmail.com

I didn’t. They looked really good. I also checked the crank bearings.

@@HopefulCanoe-yh8oo so I got mine off of eBay. I know CA conversions sells them. They have everything you would need. They also can reprogram your computer. You also need a tps sensor for that transmission

Stainless one are 350 plus shipping and mild steel one is 275 plus shipping. I have a link for marketplace in description

Yeah I have a link in the description or email me naudydave@yahoo.com

I have. I just did one on an aluminum direct drum for a th400. Wasn’t too bad to do and I also machined it for a 4l80 sprag race so I can put 4 clutches in. Sonnax make that bushing kit. I matched it so had a .002 press fit.

Thanks for the come back. I’ll give sonnax a call. I’m also looking machining and repairing the pumps not sure if is cost effective yet though. 350 & 400 pumps getting hard to find. Thanks again Bruce

Just google that. It’s for a 4t80

@@naudydave Thanks a lot!

I do. If you can message me on Facebook. I have them on market place. Just look up David Naud. I have a pic of my daughter with a nos bottle

I used a stock replacement pump. So the pressure is all the same. I didn’t not plug any relief valve. It run great now.

Yeah. I noticed it starting to get loader. I also figured I was replacing the came so I wasn’t worried about it bearing the cam up. I was deleting the vvt with the dod. Everything got a good cleaning before I put it back together.

I looked around and I couldn’t find anything out there. I didn’t make anything for them seeing I really don’t do a lot of them. Or at least I try to do th400s over them.

If I had the motor complete apart I would have. The orings probably would have been fine but the plugs are just a second line of defense. The cover is going to keep them from falling out if they ever came loose.

So I was going to Leah mine in and do all this inside but for the extra time it took to take it out it was so much easier cleaning everything and having all the room in the world. I also go to try out my new engine stand. It has the crank to rotate the engine over. It was so nice. Got it from harbor freight for $225 on Black Friday sale. Is your friends 6.0 block aluminum or case. Heads bolts don’t normally strip out unless someone was in there and didn’t do something right.

So you can install it the opposite way. It is applied in second gear. You still have forward and reverse just second gear will not be right.

If that sprag is starting to fail will it effect the way it shifts into second gear my turbo 350 has the sonax outter ring but only the 16 element sprag

Ooo bye the way it has a manual reverse valve body with no band

This is the market place listing. Just message me. facebook.com/marketplace/item/675863714184292/?mibextid=6ojiHh

Thank you for the kind words!

Well that and they really make it a little more affordable for the people just getting in to the auto racing. Sure they take a little work but most of us have more time than money.

I think I was selling them $30. I can check on what shipping would be

Do did you do a full rebuild or just installed the valvebody on a running transmission

Full rebuild was done and trans was working fine before the rebuild

So it’s probably going to be a piston seal that might of got messed up during installation. The forward drum should be fine seeing you have first gear but the other ones are tough to say for sure seeing you don’t have anything else. I would pull all apart and inspect them. I’d probably get a gasket and seal kit just to have so if they are in bad shape you can replace them. Once you get it apart you can air check it to verify what ones are bad.

Can you email me. Naudydave@yahoo.com

I have a link to market place and just message me there. I can send you my email on here if you don’t have Facebook

I moved it back to clear for a stock fan setup. I didn’t want to put electric fans.

Yes. It comes like that so you shift quicker. The separator plate will block off any of the feed holes for it. I’ll double check the instructions and let you know if you need to do anything special

So go to min 9:50 on this video and you can see where you need to tap and plug the case. You will need to do that to your transmission. It would be easier with it out of the vehicle but can be done in it. Just make sure to clean the aluminum from drilling and tapping the 2 holes.

Thank you very much for your quick response, are both tap and plug required? or can I leave the 1-2 servo in place?@@naudydave

Hold on. You might not have to do the drilling. I went to jegs website and when you click the link it takes you to a valve body without engine braking. Your retains it. I’ll have to find the right instructions

The stock case is a limiting factor in the th400 as well. That’s why they make a aftermarket case. But that’s when you have to decide if your going to take that leap. I would be building a th400 over the th350. Parts are bigger and the stock hard parts can take way more power than a 350.

I tried to find them but everyplace was sold out. I try to see what I need to do to make them work once I can get my hands on one

So I ordered it in July 2020 so prices could be different now but it was $5100. That was the wire harness and computer reflash, torque converter, tps, starter, torque converter core and shipping. I got the trans to 12 valve adapter on eBay for like $1200.

Just email me if you have any questions naudydave@yahoo.com

@@naudydave Awesome, I appreciate all the information! Do you know if this would work for a 01 gas 2500hd Silverado? I am swapping the 6.0 with a 12v and Alison 1000 6 speed.

Yea but they do have a different wiring harness and stuff for 6 speed. Also with a 6 speed you can get a display for the gear it’s in. The owner Dave and kc are easy to take to. They don’t always answer the phone but they call back everyone. They are the experts in the swap. They have adapter plates and everything so you can get it all from them if you want.

@@naudydaveAh ok that’s good to know. I definitely will contact them. I already have an adapter plate and everything else to do the swap just need harness and computer, so I’m sure they can help me out. Thanks for the information! Have a blessed one.

So I have the factory j tool. I would be willing to sell for what I paid for.

I’ve had both B&m and speedmaster pans. They see to be just the same. I’ve had like 10 speedmaster ones and only had one that had a leak. It had a casting flaw where it leaked from where they machines it. I called jegs and they swapped it for me no problem. The problem is when you buy all your parts over time and when you put it together and find a problem. More than likely your past the return date. I kinda prefer the cork gasket but there is quality of cork gasket too the thick blue one that comes with the pan I have never used. It just doesn’t feel right when you tighten it.

You absolutely can. This is so you can check it without having to put them together and put you seals on Center support or pump. All it is, is another tool in your arsenal

Once I get some time I’ll probably make something that goes directly to the fuel lever. I’m building a Prostreet s10 now and it’s taking most of my time. I have to pull my truck in the garage and pull the transmission. It needs to be rebuilt. So I’ll have some time to sit and figure out something that is less expensive and easier for me to make. I have quite a bit of time machining parts and I go through most of the holes with an end mill so they are better looking and more precise. The cnc plasma does a good job but there is still a lot of clean up.

@@naudydave Any videos on the s10? Yeah, I don't know how I'd make it either, but I'd bet everything connected right at the fuel lever would be an improvement. Especially if it were a pulley style, to eliminate the wear point on the plastic end of the cable/cables.

The only problem would be you would need a pretty long cable for it to work seeing it needs to pull towards the front of motor. I plan on making some videos on it. Just been trying to just get it on the road

In my one I bought they had no lube circuit. On a th400 they have 2 holes about the same size. With hydraulic pressure I’m hoping this one effect to much. This is all experimental. I’m going to test it. I would of liked to do a 1/8 but I’ll see what this does. Best bet would be to see a nice name brand 36 element sprag and drum and see what they did but I don’t have an extra $7-800

@@naudydave th400 has a dedicated lube circuit...its not getting oil from the clutch apply. This will be a MASSIVE hydraulic leak for the 3rd gear circuit I'd honestly be a little surprised if 3rd gear will even apply the way you currently have it

I get that. It’s all trial and error. I’ll find out pretty quick. Making an transmission tester so I can run them and be able to check pressures. Holes can always be restricted if need be.

I'd like to know the solution for this. I know the sprag needs lube oil, but where it gets it is a huge question mark to me. Thanks anyway!

It’s hard to say. I got this one that way. I don’t think it would do much. You have other parts making contact and should fill up with fluid.

good luck and keep us informed on how it works out for you.

I'm also curious. I've heard of these things burning up on guys, so I would like to know why
