Did my auto trans service about 2 weeks ago. At the end I had added about 5.5 quarts (I know hang on) of ATF+4. Everything went smooth & after I got over the "did I do something wrong" jitters of a first timer (thanks to members here!) I settled down.
Then I started to notice some odd behavior. After she was real hot (stop & go commuter traffic) I started to notice some hard shifting around 20-25 mph. She seemed to switch gears a lot between 2-3-4. It was bugging me. So I took her to the dealer this am.
This is where many, including myself, would usually tune out. My dealer is pretty high volume & the service manager actually brought the transmission guy out after he looked over my rig. He's worked there for quite a while and it's a Jeep only dealer.
He said I was a quart LOW on ATF. I told him that I had already put over 5 in and I was worried it was overfilled. Nope, he assured me she needed another quart & he was going to perform a Quick Learn.
What he told me was that the Quick Learn is a service procedure that should be performed after every transmission service. The computer actuates & times each gear shift & resets its timing and programming essentially adapting to how well its operating. I believed him because I know VWs & Audis have a similar system. I have just never heard of it before on a jeep.
Well, my commute to work was an incredible change. She shifted easily through each gear. Up and down on the highway. Mashing the pedal got results I wasn't used to & I was a bit stunned at the subtle difference.
I'll post an update in a week, but in the meantime if you have some rough shifting take this advice with a grain of salt. Everywhere I looked I read 4 quarts as the recommended amount of oil (I'm running about 6.5 now) & I'm a bit shocked. I also never heard of anyone resetting or flashing the transmission like this. Might help you out....
