Here's the situation.> I bought a 1990 Jeep Wagoneer Limited a short while ago. I was in> pretty good shape minus a known issue with the automatic transmission.> It will not usually automatically down shift into first gear when> starting or coming to a stop, but you can manually shift into the 1-2> gear and then put it back into drive once you get up enough speed (ie> 5-10 mph). The issue I have come to face since then is that the tanny> fluid smells burnt and there is an issue with the gears slightly> slipping after the car gets really warm (long, tough drives). I first> noticed this when taking a somewhat long drive (50+ miles) with a lot> of steep hills and climbs. It had more or less driven fine before that> (other than the issue with first gear) for a few hundred miles. I was> heading up a long hill when I noticed a loss in power as the power> didn't seem to be transferring from the engine to the wheels (high> revolutions) and when I looked at the heat guage I was in the red. I> pulled over and let it cool down for about 20 minutes before babying it> back home (which it made without much problem). I actually drove it> around a bit without much problem after that and decided to do a> transmittion fluid change as the level was pretty low and I thought> that could have been part of the cause of the overheating problem, and> I could check the pan for metal pieces from a tranny I might have> destroyed. When I did the change there were no metal shavings and the> jeep actually ran really well for a while after the change but the> burnt smell slowly began to return and recently when taking it on a> longer drive (same as before) the fluid did seem to get hot again,> although now that I watch the temp like a hawk I know I was never close> to overheating (maxing out at about 210), and the gears would be> delayed in engaging when you pushed on the accelerator. However, after> cooling down the car seems to work more or less fine.> Does anyone have any idea what might be the problem?> Does it look like a cooling issue with the transmission fluid?> Do you think the tranny is shot?> Do you think the issue is related to the issue with first gear?> Any comments or suggestions would be greatly appreciated.> Thanks
