4 speed draining into t-case....Awesome!! (1 Viewer)

[orin]

Hey all, just changed the the oil in the transmission and t-case yesterday. Found that the T-case was way overfull and the transmission was low. if the t-case was a 4 the transmission would be 1.5 (that would be the ratio of difference in fluid amount). i know this not the norm, it is usually the opposite. This is the first time i have changed the oil in the both since taking onwership. So now what? Check it in a week to confirm the levels again. Or start saving to change the seal and find out what is really happening?

Again thanks for your time.

Wow 4 minutes and a reply! sweet. anyway thats what i thought great. the thing is i have i have no idea how long the seal has been gone,blown or whatever. i guess im lucky. More money! , more money! more money. i love my FJ, just hopping the cash out slows a bit....got tons more to do to fix nearly 30 years of abuse.

Except it won't work in this instance since the transmission, which is uphill of the t-case, is draining into the t-case.

Same thing happened to my H55f and split-case twice. The 5 speed was getting noisy so I opened the split-case filler and wooooosh! got covered with gear oil what a friggin mess. So out everything comes and sure enough there was a good sized nick on the idler shaft seal. The seals on the idler shaft cause the problem. Nothing more nothing less.

Check the breather on the T'case - I'd bet that it's blocked.

Not only do you need to replace the oil seal, but you also need to apply RTV silicone glue to the input shaft, right behind the input bearing inner race. Then when input gear is pushed forward, it seats into a small puddle of RTV, which then prevents future oil seepage through the splines.
