2000 Durango, 4.7, 4WD Sport, 1st Generation, 197K

NO Check Engine Light / Trans was slipping between 2 and 3 with an occasional hiccup in OD(a sudden slight jerk while moving at 57 MPH then smoothed out), Changed fluidand filters, Noticed a bolt in the pan at magnet. Returned bolt to the correcthole and found the other 4 bolts surrounding it lose (center of plate besidelarge filter. Tightened bolts and continued with fluid change. After all wasback in operating order I took the Durango out for a spin. All shifting wentwell and temps are good, and the slippage between 2 and 3 did not appear.However, the hiccup did happen once. I will continue to monitor the transoperation. However, I would like to know if anyone as encountered such issueswith this particular trans and what fixed the problem.
Thank you in advance for your assistance.

 

Noted.

My hiccup was fixed by using a 2005 jeep grand Cherokee TCM. Also had hard shifts.

 

If were not aware that there is a repair kit for the accumulator cover. Mopar number 5174633AB and the kit comes with new accumulator cup and seals. The hiccup maybe from a damage seal on the accumulator cup.

 

Another hiccup today, but everything else was much better, smooth shifting and pickup. I will try your fix for the hiccup and advise my findings.

 

This is to provide you with the results after replacement of components; Transmission Speed Input Sensor and Throttle Position Sensor.
Currently all issues went away after replacing both components listed. Transission shifting in all gears are much smoother and no more hiccups in overdrive; 193K miles.
Thank you for your input.
