Hyhundai Accent 1.6 shudders in reverse badly. Pressure plate broke and is replaced. Now shudders in reverse replaced mounting still shudders

Have the transmission tested for proper hydraulic pressure. Test the valve body and shift solenoids for proper operation.

I have 95 hummer h1 and it won't shift 1 to 2

1-2 shift does not happen at WOT (Wide Open Throttle) until you let off the gas:Best case: try replacing the TPS. Middle case: leak in the 2nd gear apply circuit (servo assembly or 1-2 accumulator). Double check by using the pressure gauge and watch for a big drop when the PCM commands 2nd gear. Worst case: poor line pressure rise (see below).
1-2 Shift shudder at WOT (Wide Open Throttle); delayed or abnormal 1-2 shift; There's a problem ONLY on the 1-2 shift: 1-2 accumulator piston cracked or stuck cocked in the bore. Check the yellow spring inside the accum housing for breakage. Also, if the accumulator housing walls are scored, the housing must be replaced.
1-2 shift is delayed and harsh, may not shift into OD: TPS needs to be checked for smooth and linear electrical response over the entire range of motion. If not, this must be replaced.
1-2 or 2-3 shift is slow/soft above part throttle:Transmission is on its way out. Transmission must be removed and rebuilt.

Hope this helps

Shuddering at idle in a 2002 mercury cougar

1st to second sounds like a forced shift i would check the 1-2 shift solenoid inside the transmission and make sure the speed sensors are all in good working order, clean and apply electro grease to plugs on the transmission , as for the idle problem it could be many things from sensors for the engine to a torque converter lockup solenoid need more info is the check engine light on? you said it shudders is it missing or has a surging idle ( high and low) does it die when it goes low idle or stay running

I had the fluid in my transmission changed and they did not use type 4. They also left it 1 1/2 qts low. this caused shifting issues that have not corrected after putting in the correct fluid. I wa

I am a chrysler tech. when flashing your vehicle I beleive you update the pcm. It is a two step flash that also programs the Tcm region of the controller. This can fix some issues with coast down shifts or harsh shifts but rarely fix a trans. shudder.

Transmission skips when shifting gears

If it's a 1 to 2 shudder and 2 to 3 is fine then it's a known problem. There is a TSB about it but it's not covered under any extended warranty. The 2nd gear clutch assy will need to be re-built in your transmission. Or you can try and squeeze more mileage out of it by letting off the gas a bit at the time it shifts from 1 to 2.
