AutobahnSHO1130:
I would upgrade the computer before I did anything. The 1993 ATX computer is Notoriously the weakest link in the car, if you don't do it now, you will run into problems in the future.
Didn't want to say anything, but the H3Z is
not the weakest link the '93. If anything is, it's the tranny, not the PCM. The H3Zx is more aggressively programmed than the D4U1 and even contains "firmer" line pressure tables than the D4U1 does, stock. Any of the infamous "problems" associated with the H3Z's should be attributed to the different chipsets used and not the programming.
ftp, save a few bucks and skip replacing the TPS and ECT sensors during your 60k. These are typically
not wear items and definitely don't need replacement as early as 60k (maybe at 100k, but even then that's a maybe).
The shift kit in question is actually a **** and calibration upgrade kit made by TransGo and can be had from many places (you can read about it
here). Typically, this kit is only installed during a full rebuild since the areas that are modified are better accessed with the tranny out of the car. IMO, if you do have your tranny rebuilt and the TransGo kit installed, I wouldn't have the valve body mods performed. Go with the lubrication and calibration updates only; do not have the firmer springs or other "firming" modifications performed. For more ATX rebuild info, shoot me an e-mail or PM and I'll send some your way.
Last but not least, welcome to the club! thumb
