So If I run the motor hard thru the gears My transmission will start to buck and kick super hard, like it wants to down shift but cant. Turning the jeep off and letting it sit and cool down solves the issue completely. Is my tranny fluid getting too hot? the level is fine.

 

Start w/ vehicle identification: year; model; engine and transmission.

When my transmission failed, as-shown in this topic, w/ overheated / warped clutch steels and frictions, it also had those bucking symptoms.

No, it does not sound like a fluid issue. It sounds like two gears are partially engaged at the same time.

 

Here are my smoked / warped steels and frictions.

 

2001 Grand Cherokee. 4 Auto, Select Shift 4x4

 

Yup. 42re transmission.

 

ok the issue appeared again and this time turning the jeep off for 10 seconds instantly fixed the issue. Also reving in neutral i realized its the engine nit just the transmission, I am sure being in gear and putting a load on the engine makes it worse.

 

And you're beating on a 20 year-old horse with arthritis! What more could go wrong?
