Why does my Dodge Ram have a jerky downshift?
Valve bodies won’t fix it, nor will software updates. There is something amiss internally, either a leak or partially plugged gantry. The transmission adapts by increasing pressure, which makes for rough shifts during some gear changes. Some of us suggest a lot of test driving before buying used, don’t let them warm it up.
When does a Jeep Cherokee downshift from 3-2 to 2-1?
The problem occurs when either coasting to a stop or braking coming to a stop. The transmission will downshift hard from 3-2 and sometimes 2-1 causing a small jerking of the jeep and occasionally a light clunk. The most noticeable is the 3-2 shift which happens around 20mph with the engine around 1000 rpm (under braking, not acceleration.)

Why does my Jeep downshift at 1500 rpm?
The revs will then jump up to 12-1500 rpm as if the transmission was downshifting prematurely. Around 50 percent of the time the shift is not noticeable, the rest is a mix somewhat noticeable, to downright alarming. Fluids are fine, all up shifts are smooth as are downshifts under acceleration, and the problem is not temperature related.

Why does my car Jerk when I downshift?
Automatic transmission jerks when downshifting can be extremely annoying as you drive. Slowing down and decelerating becomes a problem when the transmission starts to jerk or clunk. This is not only annoying, but also potentially dangerous if you do not get the problem checked out.
