| Hi Mike,
Thanks
for your time. I have an 80 z28
400hp/350 th350 tranny. I noticed
that the bottom line on the radiator
had a small crimp in it. Could this
crimp cause the tranny not to shift
into drive? This all happened today;
it just stopped going into drive.
There was a good fluid level and
no burned smell; all of the vacuum
lines were connected. It seems that
it just slips into neutral once
you let off in second but first
to second is normal. I am going
to fix the small crimp, but I was
just curious if it's already toasted.
I only drove it about a mile once
it started all this and then I took
it straight back home.
Thanks for your
help!
Steve

Steve,
The line would have to be crimped off big time
to cut off cooler flow. But even if it was,
this would only cut off lube back to the planets,
and would not normally affect shifting until
the gear train is burned up. Check that you
have good vacuum and that the kickdown cable
is not too tight. If all these are OK, you may
have to do some detective work to see where
the problem is. Drop the pan and inspect it
for any wearing parts; the debris will show
up here first. 350’s are know in stock
form to wear out third gear drum bushings and
sealing rings.
Thanks,
Mike
