Mines got it and i was reading on here about them. What i wanted to know good or bad?

Good. Nothing wrong with it really, except for its general inability to reverse up a hill.

k lol well maybe mine is put together well bc its been all over the states with my dad and we aint never had a problem with it, thanks tho

and i was just looking a the window sticker and it also says 4-speed auto trans. w/lockup torque converter. I looked it up on the web and i didnt really tell me anything other then it's only available for the 45RFE and not the more common 42RLE.
so whats it mean or do? not so sure about the whole jeeps still kind of new

Doesnt mean anything special. Just means the torque converter is able to lock up thus making a 1:1 ratio between the engine and ******. Most everything has that now. Bad in the good ol days they didnt have that. Nothing special between the 45rfe and 42rle, they both have that.

Here is the way i look at it.. Considering the very small number of early KJ's, mainly 02's but a few early 03' models, that have the 45RFE, and the thousands of KJ's with the 42RLE and the very small number of failures its hard to call the 42RLE a bad transmission by ANY MEANS....

And i can name other transmissions that have significant failure rates, as i am sure others on here can, from other common makes and models. Compare any of them to the KJ with the 42RLE and it looks rock solid with a fine track record.

As for the ones that have failed, well it can be attributed to many things, maintenance, useage, basically how the person treated it. My 03' was owned by a soccer mom, was never driven hard, and just made daily trips from home in the country to town for shopping and moving kids around, it's had a pretty sheltered life. It still feels and shifts like new in my opinion.

If i were to name one failure common, common as in known by transmission shops to be a failure point, its the solenoid pack. That was the only tidbit i could get out of the shops i spoke with before buying my KJ, i did a months research before buying, engine, trans, and the overall vehicle. The KJ is not the only vehicle using the 42RLE either, which speaks even more for it, consider the tens of thousands, heck 100's of thousands, of vehicles on the road using the 42RLE and i can't say its a bad unit in the least.

All 42RLE trans owners should park there vehicles NOW,G..... forbid it ever break down,Don't drive it, leave it in a storage building,wax it 4 times a year,should last 1-1.5yr.

My 05 with the 42RLE has had a trailer (usually around 2k) hooked to it for 80k miles, no issues with the trans. Knowing how to manipulate the OD lockout and keeping the tc locked is key to making it live long.
