[Shotimes] 95 ATX Problems

[Kevin & Cheryl Airth]

Jon:
 You would think so but I have tried 3 different Ted B. versions of my LPM
and it did get worse and then he set it back to stock. I still can't get it
fixed so I understand the problem I think but lack enough knowledge on the
internal PCM programming. There is also an externally adjustable line
pressure mod that I have instructions for but it seems to only increase the
pressure. Which is NOT the direction I wanted to go for the street! I am not
sure that the chip can change what's needed. You can change parameters in
the look up table but not the relationships between those parameters. Maybe
the Tweecer could do this? The inputs for line pressure are throttle
position mainly (More throttle= higher line pressure) but how often is the
line pressure adjusted? Not often enough it seems. The regular SLO also has
this same identical behavior. Ford really should have figured this out by
now! Doug L. at FPS has stated that for less than $100 in parts Ford could
have fixed ALL the problems in the ATX. After having a FPS built ATX for
over 60K miles I believe him. The difference was and is huge!

Has anybody worn out a FPS tranny yet? Broke one? I did break mine but Doug
and everybody else I talked to had never seen this failure so I think that I
drive it pretty hard or it was just one of those rare things?  I sheared the
main input shaft that runs the oil pump. Car just coasted to a stop and
after Doug helped me with the troubleshooting, it turned out that the shaft
could be replaced WITHOUT removing the tranny! Plus it's the same part for
the SHO or SLO!
