That what I have found also, basically just a plate that may not do anything.... Reverse always engaged perfectly on this one, drive was a different story, slow when cold.
Hmm. Then I guess the reverse fix apparently did work. You just need one now for Drive Fix. :)

That is why this is a good candidate for a rebuild with a new pump. It had one issue and pump buzzing but had all 4 gears. The one outside only has first and second and was ran low on fluid.

The infamous stamped foward clutch housing. It will get replaced with a Billet Forward drum and welded on shaft

Looks like a step in the right direction. I built mine a few years ago and still running great. I also did the billet forward drum, and three clutch on the od plus the other mods you typically do on these.

You can check out my build on here. If you have any questions feel free to ask. I bought the atsg manual for reference.

One of the many important things when putting in the lip seals check the part #inside to match with the new ones. Some look the same size but have different #'s.

I visited turbo Buick performance and picked his brain on the build and he mentioned this to me. There is a lip seal tool. I used a feeler gauge.

I upgraded my snap ring pliers, one multi head POS wasn't cutting it. Got all the low reverse assemblies and the output shaft out. The snap ring against the case lugs was a challenge to remove. I also sprayed the housing with degreaser and will pressure washer the case. I will be spending $1200 US on all the upgrades after the 351 is complete
