I have a 700R4 trans from a 1988 Corvette and was wondering can I change the tailhousing from the Corvette style to a regular Chevy 700R4 tailhousing in order for it to work in other Chevy applications with no problems?THANKS

Yes, But you might have to take the complete trans apart. I assume its like a Th350 changing from a 3inch tail shaft to a 6inch tail shaft. Doug

I thought all 700R4s trans were the same length,it looks like the tailhousings are different,like they can just be swapped out.

Hey, I said I assume because I never had a 700R4 to compare. If you have the tail housing you need unbolt the old one and try the one you need. Doug

There's about 7/8" difference between the Vette & Regular. The Output Shaft may be shorter on the Vette. You'll have to check.
If it is, the Output Shaft would have to be swapped. I'm not a 700R4 guy, Trans may have to be torn down to do this. http://www.makcotransmissionparts.com/mm5/graphics/Catalog-pdf/700R4-4L60E.pdf

Bolt her up and see. Most of them are the same length, use a truck (2wd) or Camaro or B-body like Impala.
 
The extension housings will readily interchange between all 700R-4 transmissions. However, the Corvette output shaft is shorter than a conventional 2WD 700R-4 output shaft, so you will need to change the output shaft as well. Changing the output shaft requires complete disassembly of the transmission.

I have a 88 Corvette 700r4 in car and all I had to do was get the tailhousing on the right in the picture they came on Caprices of the same year and later. The housing you have was used on Corvettes and Camaros but the other piece was was needed for the Caprices to mount the 700r4 curiously never have checked the same trucks that use the 700r4....the only thing you have to remember is that when use this piece the mounting length of the 700r4 will be the same as 200r4 and TH400 and wont have to tear down the trans to make it work....you should notice that there are no mounts at the rear of your 700r4 case the were on the tailhousing at least mine where ..
