man I wish we had a forum for this...

Anyway:

I had my trans completely rebuilt. I watched the guy do it even. Also installed was a transgo shift kit. All three spacers were used.

I expected this thing to give me neck snapping shifts. It didn't.

1 to 2 was prompt, but not snappy. 2 to 3 was even less snappy.

The trans guy said it didn't make sense to put all that spring pressure on the cup because hydrualic pressure has to overcome them and it will make the shifts softer. Another guy I talked to said the same thing. In fact he said they usually put the cup in upside down, and use no springs, and the car will break your neck on the shifts.

I tried that and it made no difference. Any thoughts?

 

well, i would think that if your trannie is built, you dont really need a snap your neck shift, just a firm shift.

 

what stall are you using? A moderate stall....2600 or greater will greatly reduce shift firmness @ most rpms. w/ my ~3000 stall, the 2 washers feel nearly stock in shift firmness. Also, perhaps you need to upgrade to a vacuum modulator. That will increase shift firmness in accordance to vacuum...a must on 4l60s in high hp cars

 

hmm, had my trans out a few times now...have yet to see a vacuum modulator...

 

what year is it? In your 94 I would expest it to be fairly nasty with a stock conveter. in any thing 98 and later I would expevt TQ managment to kick in and soften the shifts

As noted a Stall converter will soften up the botom end fast till you get RPMs over the stall rating

Later
