4l80e infi
Guys,
I have been thinking about swapping out the th350 for a 4l80e transmission. Weighing the pros and cons... Any thoughts are appreciated

Re: 4l80e infi
Massive leap in technology in this swap...
Many questions: Engine it will go behind? Truck size and style? Intended use? You do know you will need a standalone control computer, to control the operation of the trans... DO you just want an overdrive trans?

Re: 4l80e infi
i understand the stand alone controller I have been looking at these off and on for a while now. Yes i want an overdrive but something that will stand up behind a big cube small block stroker.
I am not concerned with the modifications as i have done several different tranny swaps in my lifetime, how ever i am concerned with the reliability and functionality i guess. I get mixed reviews on the controllers etc etc...

Re: 4l80e infi
Love mine except the speedo drive. Maybe I have the cable bent too sharp somewhere but the needle bounces badly under 40 sometimes.
If I had it to do over again, I'd bit the bullet and buy the $600 tailhousing with the mechanical speedo drive cast into it!
