What auto trans for a 8.1 vortec swap
Hey guys I'm going with an 8.1 vortec in my 72 4x4. I want to keep it auto. Would I need to look for a 4l80e from a 4wd truck or will the 2wd version work?

2wd will work if you want a 2wd drive only you'll need 4wd one

Re: What auto trans for a 8.1 vortec swap
Is there a was? Yes, with the right output shaft and extension/adapter.
What transfer case do you plan to use?

Re: What auto trans for a 8.1 vortec swap
Yeah you can make it work. But you have to change a few things. You should be able to google it.

Re: What auto trans for a 8.1 vortec swap
If you don't know the difference between a 2wd and 4wd trans you probably shouldn't be attempting this swap on your own.

Re: What auto trans for a 8.1 vortec swap
I didn't mention, the output shaft replacement requires extensive tear down of the transmission.

Re: What auto trans for a 8.1 vortec swap
I'll skip all the technical stuff.
Is it possible, yes. Is it practical, worth it, normal, or something that anyone here would have an interest in doing...no. www.car-part.com if you can't find a 4wd trans there, then your lying to me.

Re: What auto trans for a 8.1 vortec swap
I think they have a 4WD option......you could keep your turbo400 and put a Gear Vendors overdrive behind it.

Re: What auto trans for a 8.1 vortec swap
or buy it complete and sell the 2wd 4l80e to someone else. The 2wd is technically worth more anyway.

Re: What auto trans for a 8.1 vortec swap
Or you could get a divorced NP205, and a 2wd trans will work fine. Just another option.
