Default Transmission problems

I may be havin the dreaded tranny problem rear its ugly head..

I changed out the filter and fluid about three weeks ago, the pan was covered in burnt lookin stuff, but there weren't any metal shavings on the magnet (thank god). It shifts better when goin down the road, although whenever I shift from park to reverse or drive it jerks hard if I leave my foot on the brake. Is it just the cold weather or do I need to get it looked at?

(edit) I'm at 101k miles, hit 100k last month some time.

Wake, you have a totally different trans. The 4T65E he has has a whole different set of problems than yours. What we need is someone with a bit more experience with the 65 to step up here.

My suggestion would be to drive easy in the cold, and keep an eye on your fluid.

The tranny fluid level stays good now, but I'm thinking about getting a total flush soon..Not sure what to do for it.

sometimes that can be the worst thing you can do....all the little particles that are holding the trans together will get dislodged and could possibly lead the trans to an even early death

When my 4T65E was analyzed as having the lockup torque converter control valve sticking, a total flush was not recommended by my service manager. I had changed fluid at 65000 mi.

I would do what I've done if you want to "clean" out the gunk. I changed fluid about every 10K for 3 times. I changed the filter on the 2nd change just in case some gunk and shellac had been caught in the filter. Original filter had been changed at 65K.

The first change at 80K got 7/12ths of the bad stuff out; 5 quarts of fluid from 65K change left. The next change left about 3 quarts of original fluid (from 65K change) in. The next change left about 1 quart of original fluid. But each time, I was upping the cleaner and additive level in the fluid to take out shellac or gunk. Instead of a rapid increase which might get more loose in pieces, I hope I dissolved it over time.

Now I'm at 130 K. No failure yet.

I'd like to see an example of this. I don't recall it ever being posted except in the sense that "I've heard".

Did the burnt looking stuff lokk simmilar to this?

This is friction material wear in the pan... Very light coating... That was from 2 years on the same fluid...

Also what color was you fluid, and how much burn't looking stuff was in the pan? Also notice that my fluid is still read and not black or brown...

And 4T65-E'* are in another world in terms of controls when compared to the 4T60-E...

Uhm..The fluid was dark dark almost black, hardly any red left, and there was a thick coating of that material left on the pan, pure black like coffee. It'd never been changed in the three years I've owned it.. >.> I drove it from about 50k to 100k and just changed it.
