About a month ago I was driving around 25mph when my truck revved up like it hit neutral. After this, it wouldn't budge in any gear. Every now and then it will move about an inch in drive but nothing more than that.

Is it safe to say this is definitely a bad tranny? I'm running 35 inch mud tires on 18" rims. Also the truck is lifted w/ a 5" suspension lift (CST) and a 3 inch body lift. With the size of the lift and tires I'm concerned that the stock 4l60e won't be able to last. Some people are telling me to just beef it up w/ aftermarket parts and some people don't even want to touch it with the lift and tires.

How hard is the 4l80 swap? Is this the route to go? Stock 4l60 rebuild or built would be fine? What should I do? Money is tight but I want to do it right the first time! Any input in appreciated.

Yes it has enough fluid and the fluid looks/smells burnt.

Here's a pic of my truck. Do you think I could do the swap for about the same amount of money?(compared to having my tranny rebuilt which would be 2-3k w/ labor)

Thank y'all for the quick response.

Olds88 have you dealt with PATC?
I don't know how y'all got those prices. I've called shop after shop to quote a rebuild and install and even Aamco wanted between 2000 and 2400. That was for an OEM rebuild too! All of my local shops want 3000. Are these prices really that far off?

Thanks a lot man. I talked w/ them on the phone for a good 20 minutes and they'll install a level 2 tranny w/ billet servos, a wider band, and a few other beefed up parts for 2900 w/ tax and fluids included. Not bad for what I'd be getting, but still trying to decide what route is best for the truck. That is a pretty far drive for the bottom of the boot.
