Broken TH350

I broke my trans and when I went to the mechanic he told me that I burned the high gear clutches he said that I had a leak but I didnt see any and the fluid level was ok and it had new fluid in it. what caused the clutches to burn?
What is the proper way to break in a transmission?

(Transmission mods - 2500 stall torque converter shift kit and transmission cooler)

If an auto shifts through all the gears..you pretty much just broke it in. No need for break in like a motor.

I don't see how a clutch pack burned out. Was it new? Did it shift OK before that? Usually you can have issues with modulators messing up or something causing low pressure...did it ever run low on fluid????

T-350's aren't sensitive to stuff like a 700R4 is. No TV cable etc.

I think you ought to quiz him a little more.

I had the transmission in the car for a week, it a had firm shift to it (chirped the tires every time it shifted gears) installed it on monday and next week monday during my cruising time it started to make a horoble noise when the transmission wanted to shift and it would not shift properly

The leak your mech is talking about is a leak in the third gear clutch apply circuit. It was apparantly shifting ok, but loosing hold in pressure allowing the clutches to slip. Suspect parts are apply piston seal and/or shaft seal rings.

Internal leak is HIS problem. He cut a lip seal or cracked/cut a sealing ring.

I was thinking that maybe it had an external leak and that it may have run low before you caught it.

Is he fixing it for free?
