TH350
« on: May 31, 2016, 03:54:08 PM »
I have been running a TH350 that was said to be rebuilt.  It runs fine in all gears when cold but starts to give up the ghost after it warns up in 5 or so laps.  Any idea what might be bad?  Fluid looks good but only has 10-12 laps on it.  Thinking about pulling it out.

I've got a cooler on it.  It is mounted perpendicular to the firewall under the hood.  Think moving it to get some airflow might make a little difference?  I flushed out the cooler and it doesn't leak or anything.

Yes it will help needs to be getting as much fresh air as possible. But if the damage is already done u can't save it now you'll need a rebilled

I had a fresh rebuilt TH 350 in my street stock years ago.  Sometimes it would work, other times it wouldn't.  Turned out to be a bad torque converter.  Also make sure your dipstick is correct for the pan you are using.
