b88185 Posted November 28, 2012 Share Posted November 28, 2012 My transmission sounds like it's on the way out - second gear makes loud clattering noises under load until the engine/trans are warm, and 4th-5th both make a lot of gear and/or bearing noise (sounds like a jet engine). Is this something that sounds repairable to you guys or should I just drop in a new old unit? 1985 GL wagon, 5sp D/R Quote Link to comment Share on other sites More sharing options...
b88185 Posted November 28, 2012 Author Share Posted November 28, 2012 And it's got 230,000mi on what I'm assuming is the original trans Quote Link to comment Share on other sites More sharing options...
Quidam Posted November 28, 2012 Share Posted November 28, 2012 Have you drained the oil? I know that's not cheap these days but it could tell you a lot. You may have a magnetic drain plug on it to check, then take a close look at the oil in the drain pan. I'd go from there with any other decision.

Ofeargall Posted November 28, 2012 Share Posted November 28, 2012 I drained my transmission oil and it looked and smelled terrible. I replaced it with a mix of ATF and 30 weight oil. I'll replace it again shortly. After placing the ATF/30wt mix in the case it made it easier to shift in the mornings and the detergent in the ATF will help clear out any gunk form the old tranny fluid.

86 Wonder Wedge Posted November 29, 2012 Share Posted November 29, 2012 OOF. Yeah, gear oil normally smells terrible. However, I think that 30W is ENTIRELY too thin... spec calls for 75w-90. Quote Link to comment Share on other sites More sharing options...
b88185 Posted November 30, 2012 Author Share Posted November 30, 2012 Drained the oil a while back and ran it on an ATF/oil mix to see if that helped and it didn't. Back on normal oil now and still making noise. There was definitely some metal on the magnetic drain plug, guessing that's not a good sign. If it is a mainshaft bearing failing would it be worth replacing that rather than sourcing another used tranny? Quote Link to comment Share on other sites More sharing options...
MilesFox Posted November 30, 2012 Share Posted November 30, 2012 (edited) I have a dual range trans at the shop with no car to put it in. I will have to remove it from the shop but have no where to put it! If you find swapping that easier, make an offer and take all the spare driveshaft and clutch with it. the whole unit is complete enough for a 2wd<4wd swap. This will be likely the one of one or 2 in the region for local pick up. Otherwise if you rebuild you have the option to play with gearsets. I also have a driveshaft modified to fit an ej trans if you go that route. good luck Edited November 30, 2012 by MilesFox Quote Link to comment Share on other sites More sharing options...
