Unhappy HELP PLEASE: Transmission blow.....

Hi,

WJ 2002, 4x4, 4.7L, Quadra Track

I had my WJ transmission oil and filter changed less than a month ago; everything went just fine after it, driving in the city; even I got a a bit better mpg. Then, this weekend I decided to go to a beach 3.5 hours from here. I drove at evening / night, and it just ran fine (last Friday); I decided to come back at about 11:30 am, from the beach to the city. When getting into the higway, at sea level, after about 5 minuts of driving (about 30 degrees Celcius)... I noticed the transmission failed; I saw in the mirror, a big cloud of white smoke on the rear... I stopped, and checked the mottor. Lots of transmission oil was spilled over the engine, and the white smoke was the burn oil. I don't know were it came out from... Now, it didn't work at all in "D" nor "R". No oil pressure at all. I had to tow the WJ about 350 kms back to home...

As I said, was the first drive in highway after preventive maintenance of the transmission.
I don't trust very much the shop where it was done (it is a recommended specialist in transmissions), and I'm considering to take it to a Chrysler shop... yet my wallet is going to suffer maybe...

What could have happend here? I have had this WJ for about 4 years now ... and its the first severe incident in all this time

Start with the basics here:

Drain and refill the gear box with the correct fluid and retest. My thought is that they may have overfilled the box.

If It is a gearbox failure then start looking for a second hand low miler (if you can find one that is!) get it serviced by a reputable Autobox specialist..

There are Golden rules to be followed here:

If the shop looks in anyway dirty/scruffy - Walk away!

Ask to see his "clean room" - an autobox need to be taken apart in a clean room, to allow proper inspection and to avoid contaminates going back in. If he hasn't got one Walk Away!

Remember: You pay for what you get, everybody love a bargain - but getting a good one is harder to find. If it is the tranny, and you put it into the stealers be prepared to be properly "Fleeced" and even then it could be wrong or as I've found - sub contracted to a "Dirty Shop"..

If it lightens the load:

A Guy goes into the doctor's and asks for an inspection. "Where would you like me to inspect?" The doctor asks. To ashamed to say, the man points to his rear. "Look.." He says " I've been 30 years in this game and there's nothing I haven't seen before.." So he ushers the patient behind the screens and asks the patient to remove his trousers. The man gingerly lowers his trousers and under pants to reveal the most bloodiest, raw looking rectum. "Oh my God" ..says the doctor "What on earth happened here.." "Well.." the man responds "I was on Safari in Africa and got raped by an elephant.." "I'm no veterinary.." replies the doctor "But aren't elephants tackle (Use your imagination here!) long and thin??" he enquires..

"You're not wrong there doc.." the man replies "..but he fingered me first!"

The Stealers will do the same... at around $5k for a new box.. I've seen a few over here and most just get scrapped.

Good Luck and keep us posted.

P.S My apologies to anyone who was offended by my attempt at humour, especially to the MODs it was not intended to offend anyone but to make light heart of the situation..

Thank you MadderThanMax

The WJ is still on the garden, after the tow truck left it. I have talked with a Chrysler dealer... and the shop where the transmission maintenance was done. I'm thinking to go to Chrysler... at least, they respond and provide more warranty, than a smaller shop (at leaste here, in this country). Will be more expensive... yet, for the type of sophisitcated "organ" that is an automatic transmission... I don't want to bet any more on cheaper shops.
It's sad... I really like this WJ. Hopefully is not something badly complicated. Whatever the cause was... something is sure:
The event took place, at sea level (more atmospheric pressure), at mid day (high temperatures), shortly after taking the highway...
Let's see what the Chrysler doctor have to say

Do what we do over here.. Google "Automatic Gearbox Specialists" in your area the ask for a "Review" and see what comes up..

Over here we have the problem "That its an old car..." "We very rarely see them in here.." and therefore their expertise goes right out the window.. as they have no one to service them hence sub contracting. Chrysler doctor will want to empty your wallet of all that hard earned greenbacks.. I have a car over her that's in the VW range the turbo whistles loudly.. they want a grand off me for a new turbo, but its not.. its a 100 quid vacuum hose that feeds the turbo, but they'd rather fleece you for the new turbo than the smaller repair thinking that you're daft..

Take your time, look around and see what you can find - you may be surprised!

Hmmm, i dont understand why a transmission would just puke fluid. I would say check all the transmission lines going to the cooler in the front, that seems most likely to me. Good luck i really hope your trans is fine

I just left the WJ with a specialist in transmissions; will check and provide diagnosis next week. One of the mechanics told me that one possibility, was the torque converter clutch. Long time ago the error P0740 came out; transmission went well ('til now). Could that have been the cause? He mentioned that Honda Odysseys had that issue with converter, and resulted in transmission oil expulsion and damages.

Diagnosis, was provided: the tranny pump (composed of 3 gears), just broke, and that burnt internal parts ... Major malfunction and damage; yesterday I went to see the corps. Major repair, is undergoing... not cheap at all... yet, many parts will be new in the transmission, so... ok, then. This truck is 12 y old... mechanic mentiones age (on an urban or mild use) is around 10 to 15 years, so was kind of natural, the life span it had. I don't know what kind of maintenance previous owners had on the gearbox... Recomendation is that every 20k to 30k kms, maintenance is required. I miss my Jeep, has been 2 weeks now

i had a honda with the transmission problem

they have a heat exchanger that runs trans an i think coolant so their temps stay close. that thing always breaks and ends up killing the trans, as the trans keeps running until it just dies (it starts as a slow leak)
