sertac Posted June 19, 2019 Report Share Posted June 19, 2019 (edited) When I first bought my Jeep it was shifting bit rough. Than I found out that oil level was less. When we add 1lt oil it started shifting like a dream. Lately(probably after my last off road drive I got transmission over heat light) i feel like it is having issue to shift between 1 to 2. If I am speeding properly it is shifting OK but if I am driving very slowly or accelerating slowly it shifting roughly. What I mean it is shaking the car. It is like it can't decide to stay on 1 or shifting 2. I feel like it is going 2 than 1 than again 2. I am thinking maybe since the transmission got over heat oil got bad and I need to change oil. I guess the bad option is transmission got damage. what is your ideas? Other than the shifting 1-2 all other gears shifting very very smooth even 2-1 down shift is good.

Srikumar Posted June 19, 2019 Report Share Posted June 19, 2019 As you only did a top-up the last time, I suggest to first change the oil and filter and see if it improves. 3 Link to comment Share on other sites More sharing options...

It look brownish but not so dark. I didn't smell it. I will check the smell also. 1 Link to comment Share on other sites More sharing options...
Javier M Posted June 20, 2019 Report Share Posted June 20, 2019 (edited) Sounds like a very common issue on these cars, they even sell the kits to fix that issue. Edited June 20, 2019 by Javier M 3 Link to comment Share on other sites More sharing options...
desertdude Posted June 20, 2019 Report Share Posted June 20, 2019 (edited) Well it shouldn't be brown, start with flushing, not draining and refill, but complete flush and refill to see if it fixes the issue. 6 hours ago, sertac said: It look brownish but not so dark.

desertdude Posted June 20, 2019 Report Share Posted June 20, 2019 (edited) And pray you didn't burn your 1st and 2nd clutch. When I read your offtoading post I was going to say don't stick it on 1 and 2 and keep it there for long because you might end up overheating and burning the clutches. Most probably that's what caused your trans to overheat in the first place Edited June 20, 2019 by desertdude 2 1 Link to comment Share on other sites More sharing options...

Whenever i am going around bowl or something, i am engaging it to make it not to shift. Only for few seconds. 1 Link to comment Share on other sites More sharing options...
Barry Posted June 20, 2019 Report Share Posted June 20, 2019 I concur, do a full flush, not just drain the sump and refill. If you don’t flush, you’re still left with dirty oil in the torque converter, valves etc. We have a flushing machine in the shop. Haven’t tested it yet, just saw it sitting in the corner. 1 1 Link to comment Share on other sites More sharing options...
sertac Posted June 20, 2019 Author Report Share Posted June 20, 2019 Some people are saying that flushing in higher mileage car is not good. Some saying flush is best some saying just drain and change, keeping some old oil is good because transmission got used to it. https://www.jeepforum.com/forum/f13/transmission-fluid-change-flush-can-cause-problems-618496/ 1 Link to comment Share on other sites More sharing options...
