[Shotimes] tranny question

[Paul L Fisher]

It is soooooo sloppy, Ford actually had 3 different PCM levels for a '93
ATX. H3Z, H3Z1 and H3Z2. To put that in perspective, they only had one ATX
PCM for both '94 and '95 model years, D4U1.

I used my FPS trans with the H3Z2.

Aaron,

There are many people more qualified than I am to tell you what
specifically was changed from the H3Z ('93 ATX computer) to the D4U.

Simply, the transmission shifting was improved.  The '93 ATX is
notorious for having a "sloppy" 1-2 shift.  The ideal shift for an ATX
is firm, but not harsh.  Such improvements were made in the D4U
computer.  Also, there are certain aftermarket "chip" programmers who
take it a step further, making the shifts as healthy and predictable
as possible (along with host of other modifications).  I chose a Ted
Breaux LPM, and would recommend one to anybody with an ATX.  The one
chip I would stay far, far away from would be the "Superchip".  I
borrowed one from a list member once and was not comfortable with the
shifting.  Sure, the 2-3 chirp was cool, but at what expense?  It was
a real "bang" going from 1-2!

It's obvious Ford wasn't happy with the H3Z, as it was used for only
one year.  They must've felt the D4U was better since it was not
revised for '95.  Or maybe they were just lazy and didn't care ;^)

If I'm ever out on the east side maybe I'll see you driving around!
