Usually spend most of my time on the Jeepster board but my "Jeepster puller" had a problem on a trip and I need some Chevy advice if possible. Had to have the torque converter on my motorhome replaced.1986 454 th400hd trans, 82,000mi. It started with a vibration that slowly got worse then all the fluid was dumped on the road and under carriage.(Much smoke no fire) My questions, is this a common problem for this age /combo, what are the prospects for the future, what might be the longevity of the 454. I do like to keep "old Iron" on the road but not sure what is old enough. Any info or opinions appreciated, thanks
well i cant imagine dumpign all ofp the fluid on the road is a very common problem...i mean if it were that common i doubt they would haev made any of them. as for the 454...good big block engine. they do run a bit hot and they have abeen known o eat a few cam shafts here and there since the oiling system for them is a bit sub-par, but the 44 is a very decent engine.
you might be better off makign a post similar to this on the chevy SFA forum. those guys all have solid front axles which were used in GM trucks prior to 1988. so they'd be a bit better at diagnosing for that transmission. not too many of the guys over here haev those.
good luck to you, and i hope you figure it all out
Can't say that I have any info about your tranny, sorry. But about the big block eating camshafts...it's been said in more than one place that drilling a .060" hole in the aftmost lifter valley oil plug can prevent the motor from chewing the cam to shreds. Good luck with your tranny fix.
