Turbo 350 (TH350) Information Thread

Well yes, that is certainly possibly too. It could have been bound up and caused the rear planets to explode. Nonetheless, there was a catastrphic failure somewhere in the back of the case behind the center support.

Someone blew up its behind

Stay frosty and watch your 6

Lol. But interesting. Im hoping the np203 is ok, but i suspect the failure started there because of things it did before it died. I am not worried too much but if it is a loss, darn

I still have one on my 78 lol

Hello all I have a 77 k20 turbo 350 that's giving me fits. It blows the dipstick up out of the tube about 1-2 inches after driving it even a little distance to town and back about 15 miles. Just running in shop never an issue. I just changed fluid and filter thinking that might be a problem as well as trying to clean the vent on the left side above shifter. Any ideas?

Hello 77 K20,
I am having the same problem with my TH350. Almost had a fire under the hood when the fluid hit the headers! I pulled out the vent and now the fluid just goes out there. I have to top off the Tranny often and the bottom of the trans pan is starting to rust. The fluid has removed all the paint.
I would love to hear from some experts on this as well.
Cheers,
Old Blu
