Trans shift points?

7milesout said
Mine shifts to 2nd gear too early, both at partial and full throttle. It barks the tires into 2nd even at low rpm. It shifts to 3rd perfectly at full throttle, and maybe just a shade late on the street. But I can live with that.

It's the shift to 2nd too early that bugs me.

I adjusted the cable, and it pushed both shift points a bit higher, but the shift to 2nd is still too early and I don't want the shift to 3rd any later. So I won't adjust the cable any further.

What am I looking at?

I suspect you have a spool hanging up, or a broken spring in the VB, for just 2nd to be effected like that. I assume a shift kit has been installed, OR Line Pressure has been raised, due to the barking 2nd scenario.. :)
That stated, the MOD I outlined in the previous entry/picture may not be the way to go about this. Mainly because some (TransGo) shift kits have provisions to delay 3rd in the kits programming. So, while the 2 gear shift will be raised, your 3rd gear shift rpm will be made higher than it is currently.
TransGo and Sonnax has kits available to remedy Throttle Pressure related problems. I prefer the TransGo kit # TF-TV cause it also addresses a loose TV bore issue.

available under these suppliers part numbers:
Common Distributor Part Numbers:
Transtar T22741NBK
WIT Whatever it Takes A12749N-1K
Natpro K12887D
PDQ TG-TF-TV
PTW Portland Transmission Warehouse TF-TV
Dacco, MST, D&E, and Dean TF-TV
OTS Oklahoma Transmission Supply TF-TV
A & Red's TNS-TF-TV

The Sonnax kit only addresses shift points, not bore wear, and comes with 2 springs w/ shims. That's a nightmare.

I've seen Check Balls try to drive themselves through the separator plates cause problems too. Especially on our phord counterparts..

Unfortunately, it looks like your VB will have to come out, disassembled, and inspected.

OR, replace it with a known good one. Hopefully, you have the abilities for this, or know someone competent who can that won't gouge you..
