I'm having trouble decoding the identification number on a transmission I purchased for my 96 Grand Cherokee.
Here are the numbers from the side of the transmission: PK521191082445 5341
The seller said that it is 46RE which should work according to comments I've found on the forum, but I wanted to verify that I have the correct transmission. It is mated to an NP249 TC. I simply haven't been able to locate a chart that breaks down the numbers. Does anybody have the secret decoder ring? Thanks.
Thanks for the quick reply. I added a little more info to my profile as you suggested. I'll add more later but the keep is currently completely stock.
I don't have the vin number of the donor vehicle. I've been able to find places that show where to find the transmission identification numbers, but nowhere that breaks it down enough that I can verify that I bought a 46re.
You're right Ken, after work I was able to check my original transmission which is a 44RE. Sure enough, the numbers start off PK52119108.
Thanks for all of the comments. Even though I'm new posting here, I've found this forum invaluable resource of information for the past couple of years that I've had this vehicle. You guys will never know how much you've helped others by sharing your knowledge.
The 44RE is based off the 42RE,A500,A904. The 46,47,48 is based from A518,A618,727.
I cant tell you what the difference in the 42 vs 44 is, but to get an up rating in torque from chrysler it was probably something minimal and most of the time they upgrade components that are not known for breakage. Probably added a friction disc or two to the clutch packs, wider band(s) and maybe a little more beef on the planetaries.
That's good to know tucsonzj. There may be another Grand Cherokee in my future. My daughter is learning to drive and has her eye on mine. Since we're driving old cars, I think it's best to have a spare around to drive when one them goes down. I'm not sure though what I'll be adding. I really like my son's XJ. The straight 6 and AW4 trans are a great combo.
