Car: 97 VS Ute Serries 2 193,000kms- Column shift auto Issue: See below for details, but car slips under load when hot in overdrive only Transmission serviced about 3,000 km ago when diff was rebuilt. I know there have been a few slipping trans threads, but couldn't find the exact symptoms to mine. I was towing a large fridge on the freeway so the revs where a little high than normal (about 2.5K). The car would slowly increase the RPM before it would start to rev out. This has happened once before, but pulling over/turning the car off and on has previously fixed it (mind you my other issue is car wont crank over when it's warmed up, so battery goes flat trying - not fun on the side of a freeway 2.5 hours from Melb with no prick pulling up to give me a jumpstart!) The whole way home it seems that once under load like going up a hill sitting around 2.5K, same issue would happen. Sometimes backing right off to lower the revs then increase it would behave for a little. Seems that when I left it in 3rd gear sitting on 3K, it drove normally (except I sat on 90-95 in a 110), and putting in overdrive downhills worked. As this only happens in overdrive, is it the trans starting to go or possible stall converter issue? I checked codes last time this happened and nothing, but will try and check tonight. Also haven't checked colour of fluid. Thanks in advance.
