I like the blue marine cap as well. have yet to have one of them fail me, but many of the black ones give all kinds of grief. ANYTIME there is a torque converter issue with a 95+ 4L60E the valve body should be teh FIRST thing addressed. Most any trans shop knows this, and I'm surprised one told you to do a converter instead of the lockup valve. It wouldn't hurt to put a TRANSGO SK or HD2 shift kit in teh valve body. Lockup will be alot firmer, but it will eliminate the possibility of converter slippage from a control issue which is a semi common issue on 95+ 4L60E's. And it wouldn't hurt to put a fuel pressure guage on it while it is doing it to make sure it is holding pressure. If it still has teh central unit with poppets on it, they NEED at least 42 PSI to open the poppits properly, but prefer 46 or better.
