Turbo 400 to Transfer Case - The 1947 - Present Chevrolet & GMC Truck Message Board Network

hexafamily · 02-23-2007, 11:54 PM

I am looking at a '82 Jimmy originally a diesel but converted to Chevy 350. The owner stated the 400 trans is bad, but has another 400 but its a 32 spline output shaft instead of the 28 spline that matches the transfer case. Any suggestions on how to match these up or should I just get the 28 spline rebuilt? I was unaware there were two different types. All input welcome.

Thanks
Don

If you feel up to it, you can swap out the input gear to match what you already have. Are you replacing the x-fer case too? If it was already attached to a TH-400, it should have the correct input gear. As far as I know, the 700R4's and TH-350 had 27 spline output and the TH-400's and SM-465 had 32 spline output.

if it originaly had a th400 it will match the tcase !!!unless!!! he is retarded and is giving you a 2wd tranny with the wrong out put length.

or he doesnt know that he had a 350/700r4 [like said before]

Thanks guys, you answered what I thought. I am familiar with two wheel drive trans, but not four wheel. I will find out what he has today.

What is wrong with the Transmission?
The diesel torque converter is all wrong for a gas engine.

This is just something to check out before spending too much.
