CrewCab Tranny Question...

Okay, On boot leave from Parris Island, I bought a '79 Crewcab in rolling form, no motor or tranny. It had a TH400, and I was told that it aint no ordinary 400, it's even longer than a longtail th400, because of the extra length of the truck they made the tailshaft and output shaft longer, does anyone know if this is true, or if a regular longtail Turbo400 will work??? Thanks
Brandon

Crank,
Hope someone will be able to help with your truck, I don't know about crew cabs. I just wanted to say OHRAH. And thank you for your service to this country. I was a Drill Instructor in the early 70's at Parris Island. And after 8 years in the Corps got out a GySgt.
So Semper Fi and GOD bless

Re: CrewCab Tranny Question...

I'm pretty sure the difference is in the length of the driveshaft, not a different tranny.

Yes its a th375. Its pretty much a th400 but it has a longer tailshaft and the output spline is the same a th350. Its also relatively the same length as a th350 9in tailshaft.

The regular 400 works GREAT in mine! Make sure the splines match before you try to install but other than that have fun!

Re: CrewCab Tranny Question...

Alright. Well just keep me in mind if you wanna part with it. I need one for my truck cuz it was taken out by the previous owner for his other crew, I'd like to put in what came out of it. So if ya wanna part with it, give me a holler
