Default Re: Your ZF6 makes noises or won't shift, what to do?

From my notes on another computer I'll just stick with the LT5 S6-40:

thru '90 the part # on the tag should be 1052 000 031, '91 1052 000 035,
'92 1052 000 045 now the confusion, early '93 1052 000 045. These are all 610 Nm assemblies.

later '93 1052 000 047, '94 1052 000 081 These I believe are "black tag" 540 Nm and still have "lift ring"!

The only LT5 crash through "blue tag" '95 1052 000 087. No lift ring.

I guess I'll be embarrassed as hell if this isn't correct but I do believe it should be. I would guess there will be some crawling under the car this weekend!

One other point that interests me. I never thought you could just swap a connector to use the later speed sensor in the '90 cars. I thought the '90 cars were maybe 2000 pulse DC (sq wave) and the '91 and later 4000 pulse AC (sine-wave). I don't know this to be fact but it's the way I always thought it. I went to a good bit of effort to buy an original spare from Vauxhall for a Carlton that shared the ZF transmission with the Corvette. It arrived in an original Delco package. It was a very good find and the parts guy from Vauxhall was astonished that I found him. He had NO ZF stuff and the Carlton people I've corresponded with say the parts are likely harder to find in GB than they are here.
