Looks like I'm getting an 80e. A guy at work has one that was pulled from a 1ton gas burner. Trans is in good shape, and he only wants $200 for it. He really just doesn't know what he has. I am kinda new to this so I'm not quite sure what I need to do to make this trans worth while behind my 4.8. I'm sure I will need a stall but not sure which one. I plan on driving in town some and towing. I still need to maintain the functionability of the truck. Future plans are a maggie, cam, gears, locker. Not sure what all else as of now but it will be a slow build. Will this swap be better done at a later time? Thank you in advance.

 

If you are planning to run a maggie, don't over stall. 2600 to 2800 is whats recomended. I'm installing the full Transgo HD2 in mine and running the stock converter behind my TVS. Seems to be a pretty good combo for some decent hp. What year is the 80e? Sounds like one hell of a deal.

 

I think he said 06? I'll get better details tom. What does the trans go hd2 do for it?

 

It's the most popular shift kit for these transmissions. It improves feel and durability, esp with the recomended pump mods.

 

200 is highway robbery on your part. Good for you. I paid 350 for mine in good used condition. It was from a 96 with a mighty 6.5 diesel in front of it. Seeing as how it came from a gas truck give the stock converter a try before you go changing it. From what I understand they stall around 1900-2000 which isn't bad IMO for a stocker. I am using the low stall diesel converter in mine that only stalls to 1500. It had worked great for me but I just installed a LT4 hot cam so a stall change may be next.

 

+1.

Congrats! A stock 4L80e is pretty stout in stock form.
