Is anyone having the same problems. I try to keep her tuned and running ok.
I have 76,000 miles on her. I recently had to have the intake gasket
changed, and did the plenum pan as well, and had the catalytic converter
replaced. What Im noticing now, is that fast accelleration, seems as if Im
starting out in 4th gear. Big delay in take off..suggestions?
I didnt try that, but what I have also found, is that when tried to pass,
or jumping on it, she downshifts, but goes through the gears to fast.
Kinda like she's slipping? I had a trans flush done, that B&G stuff..talk
to me about that govner though..please...
OK, short version
Mopar elected to keep the same 'basic' valve body that has been used forever
in the 904/727 and added a piece on for OD and lock-up with the advent of
the 500/518 units
then they decided to stay with it when they went to the 'electronic
the vehicle speed sensor tells the ECM what the speed is; the ECM tells a
'governor pressure solenoid' to generate a hydraulic pressure corresponding
to vehicle speed
so far, so good, if they'd stopped there............
but then the 'diddle with it' urge overcame common sense, and they added a
'governor pressure transducer' to feed back the GPS pressure to the ECM, to
'see if it was working right'
unfortunately, the GPT doesn't read the pressure right (thinks its too low)
and the ECM tells the GPS to jack up the pressure
a scan tool will show 'governor pressure' of 20, 30, even 50 psi at stop,
when it should be zero
result is 2nd, 3rd, or even 4th gear starts
get a scanner on it and watch the 'gov press' line when it acts up
