T56 adaptor plate from the gear box?

[skullcrusher73]

Has anyone used this when doing a conversion? The adaptor plate has a muncie bearing retainer. How do you remove the T56 bearing retainer ? Or are suppose to?
Can anyone tell me the correct way to install the adaptor plate? Thanks for your help!

It works great, I did use one last year. You bolt the plate to the bellhousing with the supplied bolts the just bolt the trans up. The retainer stays on the adapter plate. Make sure you do 2 things, Get the extended pilot bushing and No.2 take 2 3" bolts and cut the heads off and then cut in some straight slots so after you get the trans in you can simply trun them back out. The reason for doing this is because as I found out that the T-56 is heavy almost Turbo 400 heavy. once you get the input into the clutch after it's lined up having the blots to slide the trans on makes it real easy.

What you think might be a retainer is accually the TO bearing. Just unbolt everything off the front of the trans untill all you see is the input shaft so it looks like this and you are ready to bolt the trans up.

You are very welcome, When I first looked at doing mine I thought it would be hard to do but it turned out to be pretty easy other than I had to take my tranny out 3 times due to problems with the first one. If you are doing a second gen you may have to cut the floor to make it fit. On my 1st gen there was plenty of room.

I got everything set up and had a major set back . When I traded for this T56 I was told that it was a 98 or later tranny. It looked so clean I took the guys word for it. After installing the adaptor plate I realized the input shaft was to short. So now Im in the market for a 98 or later input shaft. The Gearbox is backordering theres currently . If you know where I can find one let me know.

Thanks for insight and the pics!

I believe you had to have a pre-98 t-56 to use this plate without changing input shaft. Well i have the same plate and a 97 t-56 that i am not gonna use if you want to work something out as i have changed directions on my car since it is so close to original. Or just change your input. If interested just email me as i am in Dallas.

The adapter plate will not work with an LT1 trans 97 or older. It is made for the LS1 trans so one would need to change the input shaft and front plate on the tranny, Not a big deal after taking 2 apart last year.

Thanks for everyones response and insight. My t56 is a pre 98 unit.
I found after searching far and wide an inputshaft for a 98 /later t56.

If you read this can you give me insight into correctly installing a later input shaft?

Is there any shimming or any technical advise you can give me?

Thanks!
