Good observation on the clutch. I also replaced the clutch fluid while I was down there (color tells me it had been in there a while). This is probably why my shift into third is better. And yes - my slave is wet with fluid on it - looks like it needs to be replaced at some point (its a 91 style - has already been replaced).

I will swap the factory MEMCAL back in - it didn't help any when I was chasing the issue last year (before I fixed the TB and ported the top end).

Looking at the FSM - I think I will try disconnecting the ride control module - it also ties into the VSS signal . I doubt this is my problem (because my speedo seems to have no issue at all - so I think the VSS signal to the ECM is good). Even though ECM self check is good - this seems to be the most probable cause. I'm afraid that getting an ECM is going to be tough.....
