T56 Write UP

[Gadget]

Did a few short drives over the weekend. Looks like this new combo is working very nicely.

Had a T56 Magnum built with these ratios:

2.97 2.07 1.43 1.00 .74 .63 and running with my 4.10 diff ratio

The outer casing is just like the Camero version I had. Rear mount, shifter and so on all the same. Even got the same input and output splines so everything bolted right up.

Now I have an extra T56 transmission freshly rebuilt with about 1000 miles on it. Wonder what I will do with that???

Trade with me for mine that has unknown mileage and unknown parts!

That is great to hear Gadget. And now that you have that nice 4.10 rear gear, you will be able to make it to The Texas Mile. . Or something more local to yourself.

Maybe, call them and ask.

This thread is to discuss the technical aspect of the swap only

My TOB started squealing at XFE, it does it especially when its cold and I have to slip it on a hill.

I know I will have to address it sooner or later so I have a question:

How much variation in the measurements could I have? Rather then dropping the trans and measuring, then putting it back together, then getting spacers, going through it all again.....

Anyway, could I order the .75 spacer and then a few shims to have on hand and do it all at once?

 

[Gadget]

Yep, you could do it all at once.

I have an extra thin shim if you need it. No idea what I got two of them.

Just from the feel of it, the GM unit that Coupe suggested feels like a much higher quality unit.

what shims should I have on hand "just in case"

What clutch options to you have right now G?

 

[Gadget]

My guess and guess only will be get the same thing that Coupe and I are using.

We both came up with the same measurement and spacer thicknesses. He has an OEM type clutch and I have the URD TwinDisc so I am sure you will be right in there as well.

Like I said, I have an extra thin one if you need it.

I have a new URD Stage 3 disc (T56) in the garage as my back up, if Mr. Dog does not have one in stock.

Tick offer a 3 pack of shims. I would buy this along with the 3/4" spacer and you should be good to go.

This is Tick's 3 pack.

Gadget, did you buy the spacer from ram clutches or did you have one machined?

Ill probably save the clutch upgrade actually, dropping the trans is a yearly event at this point so I want to make sure I have something to do to it next year lol

 

[Gadget]

The thin spacer I have is a pretty red and I got it from AMS.

[revobreaker]

no no, the .75 spacer

I will want to snag that thin one tho...

That's what i did. You could keep the same diff and just change the ring and pinion to suit your needs
