Hi guys to get more feedback i decided to start a new thread to explain the troubles i am experiencing with my transmission, i have read through the numerous posts although some seem to have similar symptoms as mine i thought i would describe exactly what is happening with mine, so i can get the most accurate responses..

Ok so the car is a 2002 TJ magna with 4sp auto box, for about a month or so when the car was driveable, it was slipping when trying to change gears, it was most noticable when you come to a complete stop and then proceed to take off again, it would rev for about a second or 2 before engaging into gear. As the time went on it got a little worse, sometimes would drive faultlessly, other times it would not engage for quite a while..

Another symptom i noticed was that sometimes there would be noise coming from the transmission, best i can describe the sound is almost like when you have bad / warped discs on your brakes and they are rubbing whilst you drive, this noise would happen only sometimes, and mainly on start-up or when reversing out the driveway, the noise usually disappeared once you would be driving for a while..

One day, i was driving along and the car lost all gears, no drive at all. Pulled over had a quick inspection and noticed that i had left a trail of transmission oil behind me. Towed the car home and on further inspection i filled the transmission up with some oil, then degreased the transmission so its easier to see where the leak is coming from, i started the car and after about a minute there was a constant stream of fluid leaking out from the area where the transmission is attached to the engine.

With these symptoms in mind i was just wondering if anybody has some insight as to what could have caused this.

Let me just add, there are no obvious cracks or damage to the transmission, i have removed the transmission from the car and was thinking of buying a new seal kit to replace the seals in the general area of the leak, but just wanted to get some feedback to see if i am heading in the right direction, or if there is a good possibility its something more serious...

Any help on this matter would be greatly appreciated..

Cheers,
Laz.

Sounds like you have a few issues, one of those being the planetary gears being on the way out and the second the oil pump seal having let go, possibly due to the oil pump itself being about to also let go

best option you have is a good used trans

That front seal leaking isn't the problem, the problem is why it is leaking.
The leak past the front seal is a symptom of bigger problems.

As above, the box needs reconditioning or replacing. Probably cheaper to buy a box off Mal.
