Bowing down to the Truck gods ~

I am by no means a "Truck God", I have however messed with enough **** to know that burnt fluid is no good and is a result of heat damage. Search the forums and look at the #1 killer of a 4l60, its heat. Why do you think people put 40k coolers on stock trucks? When you go over 200*F its not good, when you go hot enough for the dash warning light to come on your fucked, maybe not right then, but its a matter of time.

Am I saying his transmission is totally fucked...no. Do I think its damaged....yes, Do I think its driveable with just a fluid change....maybe, Would I invest a shift kit and a brand new coverter in it......hell no. At least not without freshening it up.

Black / burnt smelling fluid = no bueno. Thats why my TBSS is getting a new trans as we speak.

your looking to see if you have any grooves or nicks in the bushing if so you'll need to replace it.

jumping on a 4L80 by any chance?

I was Going to but every shop i talked to said the 4L80 will actually hurt performance if you don't have enough power.. I will have about 500-520 rwhp after this next round of mods and I probably won't be going much higher than that for a while. I'm getting a fully built 70 built for 700hp so I should be ok. Maybe it's different for a TBSS cause only TBSS's with big power are runnin a 80 but i see alot of guys on here runnin it with alot less power..

The trans I am talking about is the 4l80e I purchased from an auto shop.
My current trans a 4l65e has pretty red fluid and it has aout 46k miles

Ahh, I still feel the same about the 80, heat kill transmissions.

I also frogot to mention that my 4l65e had a factory trans fluid which is why it was still red
