well, I realize that it's about time for a rebuild or a new tranny altogether. but... I don't have a job right now.

so... my dilemna. everytime I accelerate, it seems that my tranny decides to drop two gears and then the P on the tranny switch thing flashes a bunch of times. then the tranny slips back into the correct gear and I am off, but it is happenning alot more regularly now a days...

 

Is there a tranny diagnostic you can do?

 

yes...yes there is..forgot how.

 

how many miles you have? i have 101k and i do alot of rough driving (stop and go...alot of shifting - auto btw) and it seems the tranny is still working like a dream...i wonder if i should start worrying

 

I have 160k on original tranny no rebuild.

Thing has been babied it's whole life.

Just now it is starting to shift hard into 2nd. Had it cleaned out at Woodfield Nissan and now it only does that when it is cold.

 

hmmmm, I'll take a stab at it.....the light flash usually indicates an electrical prob, thus maybe you're not in as much trouble as possible.

the diagnostic from the Haynes says:
let car warm up, turn car off, turn key back to ACC, watch "P" light and count blinks:

Flash: Symptom:
First Revolution sensor circuit bad.
Second Speed sensor circuit bad.
Third Throttle sensor circuit bad.
Fourth Shift solenoid A circuit bad.
Fifth Shift solenoid B circuit bad.
Sixth Timing solenoid circuit bad.
Seventh Lock up solenoid circuit bad.
Eighth Fluid temperature sensor disconnected.
Ninth Engine revolution sensor circuit bad.
Tenth Line pressure solenoid circuit bad.

 

that did work out, heres the list again

First flash:
Revolution sensor circuit bad.
Second:
Speed sensor circuit bad.
Third:
Throttle sensor circuit bad.
Fourth:
Shift solenoid A circuit bad.
Fifth:
Shift solenoid B circuit bad.
Sixth:
Timing solenoid circuit bad.
Seventh:
Lock up solenoid circuit bad.
Eighth:
Fluid temperature sensor disconnected.
Ninth:
Engine revolution sensor circuit bad.
Tenth:
Line pressure solenoid circuit bad.

 

Thanks man.

 

I had to rebuild my tranny at 125K - largely due to neglect....
never changed the tranny fluid since I bought the car @ 50k !

plan on doing a drain and refill with REDLINE racing ATF today..

 

does this apply to 89 auto trannys?
i dont recall my car ever having a flasing P

 

yes...as far as I know all 3rd gen automatics have the P/C switch and alert the driver to electrical malfunction!

 

ohhhhh that P, i never look at that when i start up my car

 

yeah, i'd start saving...

 

Heh, I'm at 127k original miles and my tranny is doing just great. Only problem is I friggin hate it...

Stupid auto's.....I wanna swap...
