First of all thank you for your time on this as I am very "skimp" at the moment. As for my car it may very well be in second gear but engine rpm is not excessive although take off is very slow.I do not seem to have a "check engine light" on, perhaps I should connect a code reader to the port for the heck of it? This is a listing of diagnosis given on estimate
atf1= atf clean
sh1a= shifter (prndl) indexing correct
dtc2= dtc, s no communication
dr= harsh reverse engagement
r3= third gear starts
q4= no 3-4 upshift
q7= no lockup
low coolant light is on but system is not low
I have checked ground side of relays to fuse block for continuity (all good)but have not checked source side to pcm (were is pcm?) Could a single broken wire on one solenoid cause such a condition (no lockup, no shifting, high line pres ect)?
The only inside wire I can think of other than the valve body solenoids would be the clutch for torque converter lockup, that's only part of the problem and that should throw me some codes!
Faulty gear shift selector switch should also throw me some codes, am I correct? Also faulty turbine(engine)speed sensor should give me codes? Possibly fried bulb in check engine light(better borrow me a code reader) this seems unlikely to me.
Faulty ground strap to tranny? Test light says "no" but that's not the same as a big thick strap! Don't be afraid to get to teki on me as I have worked in electronics field for a time(repaired smt machines) but autos are not my forte again any insight into this is welcomed (even more by po boy like me) thanks.
