Hesitation - is it a trans issue?

When driving my '85 IROC (with an aftermarket 700r4), I have noticed a "hesitation" around 40-45mph. I have stared at tach when this happens and it does not budge so I'm guessing it's not an engine...

Hydralic fluid embedded in paint?

I bought a white iroc that had been sitting in a garage for the past 15+ years. When I got it home and started to clean it up, I noticed an oily residue on the paint. I called the previous owner...

Re: Starting an engine after sitting for 14 years.

Re: Starting an engine after sitting for 14 years.

Re: Starting an engine after sitting for 14 years.

Thanks for the heads up. I'm guessing (more like hoping) a cracked flex plate (or loose bolts) wouldn't require anything other than replacing the flex plate?

Re: Starting an engine after sitting for 14 years.

I will take a test drive in the next couple of days and put it under an actual "load" to see what happens with the knock. I suspect that, despite the oil pressure readings, it's probably a bad rod. ...
