4 Wheel Drive/SUVs: rear transmission seal, automatic transmission fluid, rear seal

Question
99 Wrangler leaking gear oil.  I know it's the transmission and not the transfer case.  How in depth is it to change the seal (is there a seal or is it silicone, etc)?

Answer
Ron,

The first thing I would suggest, is that you purchase a repair manual for your Jeep.  They can be purchased at most automotive parts stores for $20 or so.  This will give you step by step instructions on replacing the seals.  I'm not sure which transmission you have, but if it's stick shift, it will have an AX 15 with a six cylinder, or an AX 5 with a 4 cylinder, unless you have an automatic.  It is possible that the leak could be a front seal on the transfer case, as both trannys, and the transfer case should use automatic transmission fluid, and the leakage will look the same.  Both of these transmissions have a rear seal, and a front seal that can leak.  They are both relatively easy to replace, but you will need to pull the transfer case to get to the rear seal, and the transmission if it is the front seal.  It helps to have a seal puller, and a seal driver when replacing them.
