Current vehicle (don’t laugh) 1995 Toyota 4Runner V6 automatic 4wd with 210k. Named Hi Ho Silver but Silver will not get out of his own way much less pull a trailer. ATC light comes on, on long pulls and he pukes transmission fluid. Has had trans cooler flushed and transmission drained and filled but afraid to flush transmission for fear of loosing transmission. Just had new catalytic convertor, muffler and tail pipe installed improved performance slightly. Did not improve ATC problem. Toyota can’t duplicate problem but won’t send tech with me on a drive along. Not that I truly expected that but I can duplicate .
Any Ideas guys? Please help lady in distress
