Hello everyone. Glad to be here. Looking to upgrade transmission from 400r to 700r. Is this possible for a 1981 g20 1ton? Seems to be the drive shaft is too small and the ubolt is on the wrong side of it. Thanks.

Welcome to the site ..... I have 4L80E in both of my G30 1 tons .... maybe a 4L60E would be good.


Again welcome

Question is it a G20 or a G30 .... G30 is a 1 ton a G20 is a 3/4 ton

Then it's a 3/4. Says sportvan on the side. Are those 4speed?

I can not seem to figure how to post pics? Either way I might sell it and get a newer model.

What lift kit for a g30 do you recommend?
Posted By: frscke1 Re: Hello. Need help with 81 g20 - August 07th 2020 9:22 am
there is no "kit" for a G30 .... mine is a solid axile N leaf springs ... 2" body lift and a 1" suspension lift .. done by 4Wheel in Salt Lake City for the Govt before I got it.

There is a thread that A guy is tryin to lift a G20 ....

How is that working for you? I go off-road a bit. And want to travel with it. How's the performance?
