95 GC transmission probs
I have a 95 GC w/ I6, after the engine and transmission warms up and I
get to highway speed the revs will cycle between 2,000 to 2,100 rpm
(even on cruise), then randomly the trans will shift into 3rd and run
at 3,000rpm. This does not seem to be load dependent, it will down
shift on a fairly steep hill while I'm backing off the throttle. This
transmission has about 20,000 mile (rebuilt). The shop couldn't find
anything wrong. They asked about having another shop check it out the
engine and transmission codes I agreed. Well nothing other than "high
secondary ignition resistance". I tuned it up plugs, wires, cap and
rotor, it was also suggested I have them perform "fuel injection
system flush". The transmission shop "is happy to fix it under warr"
but doens't think the problem is in the transmission and claim the
computer is telling the transmission to down shift? While this could
be true downhill with no load makes this hard for me to swallow. Any
insight or direction would be appreciated.

Re: 95 GC transmission probs
Hi Andre,
Most transmissions will hesitate to shift into first, then second
when they're one pint low and cold, you might double check it hot. The
site the describes the transmission module is at:

Re: 95 GC transmission probs
a throttle position sensor going bad will also do the exact same thing..
consider looking at that

I always say VSS (vehicle speed sensor) for these symptoms...

Re: 95 GC transmission probs
I'll check "TPS" although I believe the transmission shop checked it
as the mentioned it as their first thought. The fluid level is good.
thanks
