I have a 2000 Grand Cherokee (WJ) and I am trying to figure out what model of transmission I have. The reason is because I need to change the fluid and I want to drop the pan and replace the filter. The Jeep has 85,000 miles on it and is used mostly for my girlfriends commute to work, round trip 30 miles. I am a fellow Jeeper. I started with a 77 CJ5 as my first car when I was 16, rebuilt the tranny back then with an old blind guy that knew everything there was to know about them.
Anyway, a few days ago my girlfriend started noticing some "slipping" in the tranny. She said it clunked into 2nd or 3rd gear, not hard, but made a sound you don't normally hear. I confirmed this last night coming back from Cinqo de mio, forgive my bad Mexican grammer.
Sure enough when you take off from a stop sign at a normal chop, and keep it around 20 mph, it clunked into what felt like 2nd or 3rd. Not very loud or hard, but enough to be a problem.
I have a Haynes manual for this thing but I can't find anywhere what model the transmission is. I went to Autozone tonight and they could not tell me, either it was a 45rfe or not. And the tranny fluid was for a 45rfe or not. A lot of help they were.
So this is what I need from you guys out there in Jeep land:
1. Help me determine what model the tranny is.
2. What type of fluid do I need and how much is required when I drop the pan?
3. Should I add any other additives to this?
Also, could the bands be loose or causing this problem? Again, the Jeep has about 85,000 miles on it and I don't think the fluid has ever been changed, if it has it was flushed about 40,000 miles ago.
How do I get all the fluid out of the system? I know not all of it comes out when you drop the pan, so how is this done other than flushing?
I have a local Jeep dealership in my town so I can get the parts pretty quick if need be from them.
Thanks in advance for all your help.
