89-95 Toyota Pickup/Hilux. Manual transmission and rear end oil change. Recently had some work done at the local Toyota dealership. They recommended I change my manual transmission and rear end oil, which they were happy to do for $160.00. You must use GL-5 in the differential(s). You can use either oil in the transfer case (if you have.
Just finished my first long trip in the 62. DC to Cleveland.
Was pleasantly surprised to average 16mpg door to door (up from 11 in mixed city/hwy driving).Noticed an odor of gear oil when i got to my destination, and also the hatch glass has a very light coating of oil. I knew already i had a leak, so thought i'd check the tcase to see if it needed topping up. To my surprise it was overfilled pretty significantly.
I'd say there is about 14-16 ounces too much. Also the color was pretty black. I THINK this is all gear oil (i.e. Not contaminated with ATF); it smells like s. and has no reddish hue to it. I'm too inexperienced to tell based on viscosity though. It's not wattery, but it's not really thick either - i'd say about the consistency of 10W (cold).
Few questions for this newb.1) Did I use the correct bolt to check the level? In the pic it's the one behind that corrugated metal hose cover. You can just see it facing to the right (rear of truck) of the pic.2) How do I know if it's ATF mixing in?
Continue to check? Assuming it is ATF coming in, it will continue to overfill, and eventually turn red, right?3) is it possible PO over filled by that large an amount? I'm thinking if it was filled on an incline, it could be possible.4) Am I okay to make the drive back to DC with this issue? It's 380 miles. Anything I should keep in mind on my trip? Things to check or monitor along the way?thanks for your help.-b. Just finished my first long trip in the 62.

Anything I should keep in mind on my trip? Things to check or monitor along the way?thanks for your help.-b. Your pics didn't come through.Did oil come pouring out the fill hole? Its just to the left of the idler shaft on the back of the case. Idler shaft is the one with the small bolt and usually a ground wire attached. Your description sounds like the correct fill hole.Odd that there would be so much excess as its virtually impossible to overfill. Could be getting ATF through the seal but not very likely, usually when the seal between the auto and the tcase fails it pumps 90 wt into the tranny.
Check the tranny fluid. Was the extra oil foamy? That could account for the extra. And it could have been too light of an oil.Drain and refill your tcase to the proper level with 90 wt and you should be fine driving home. Check it when you get home, if it is leaking ATF into the tcase it took thousands of miles to get there.
The seal between the tcase and tranny is not a simple fix, requires disassembly of the tcase.Are you sure that the oil on the hatch is gear oil, Not ATF? And yes old 90 wt smells horrible, especially if it has not been changed.Tony.

Pics should be up now.yup, oil came pouring out the filler hole.i've checked the tranny fluid a few times since i purchased in january, and it looks normal (also looked okay according to my mech who pulled the dipstick before i left). I checked it after driving a 150 miles on the way here, and it looked alright. Check out the attached which i snapped just now (it shows a little cleaner in the pic than what it really looks like). If there's any gear oil in there, i imagine it is a very small amount.the oil was not foamy. This was drained after sitting overnight - the fluid was cold.the oil on the hatch smells the same as what came out of the tcase.i will change out the oil today - heading back home tomorrow.thanks for the quick replies everyone.-b.
