91 Imperial not shifting

I have a 91 Imperial 3.8 with a 3 sp OD transmission. Transmission was new in 2001 - has 40,000 on it now and is serviced regularly. It is not shifting gears - park, neutral, reverse are ok, but not shifting out of low. It seems to be an electrical problem - computer is not getting power on pin #II.
Any suggestions greatly appreciated!
Thanks

do you remember what kind of fluid is in there? If it's anything other than Mopar ATF +4, you'll have problems b/c the solenoid pack that controls the gearshifting on this tranny can't flow the fluid properly and it causes chaos to develop.

ATF+4 is for 2002 and newer vehicles. All of the 1990's Mopars take the ATF+3 or 7176, I recommend you take it to a ATRA listed Transmission Shop for a proper diagnosis. Could very well be a bad turbine speed senor. If your speedometer is working properly and it still eill not shift properly then that is a strong possiblity. Usually it will be either the Input or Output Turbine Speed Sensor for this problem. Not a expensive repair either! If you need help finding a ATRA Transmission shop drop me a line and I will help you find one.

Actually, ATF+4 is to be used on pre-2000 vehicles. The only exception is 1999-earlier minivans. Everything else is supposed to use Mopar ATF+4, I have the TSB to prove that:

NOTE :THIS BULLETIN APPLIES TO ALL VEHICLES EQUIPPED WITH CHRYSLER AUTOMATIC TRANSMISSIONS EXCEPT 1999 AND EARLIER MINIVANS.
DISCUSSION:
A new transmission fluid (ATF+4(R) - Type 9602) has been developed and is being used as factory fill for all vehicles with Chrysler automatic transmissions. Until now, vehicles originally filled with ATF+2 or ATF+3 were to be serviced with ATF+3. Effective immediately, it is recommended that all vehicles with Chrysler automatic transmissions except for 1999 and earlier minivans be serviced with ATF+4(R). ATF+3 should continue to be used for 1999 and earlier minivans because of the potential for torque converter shudder during break in. For all other applications the ATF+4(R) fluid offers significant benefits as outlined below.
NOTE :ATF+4(R) MUST ALWAYS BE USED IN VEHICLES THAT WERE ORIGINALLY FILLED WITH ATF+4(R).
NOTE :SERVICE INTERVALS DO NOT CHANGE. THE SERVICE INTERVAL CURRENTLY IN EFFECT FOR A GIVEN VEHICLE SHOULD CONTINUE TO BE FOLLOWED.
NOTE :ATF+4(R) IS COMPATIBLE WITH ATF+3 AND CAN BE USED TO TOP OFF VEHICLES THAT CURRENTLY HAVE ATF+2 OR ATF+3. DO NOT USE ATF+2 OR ATF+3 TO TOP OFF VEHICLES THAT HAVE ATF+4(R) FLUID.
BENEFITS
^ Better anti-wear properties
^ Improved rust/corrosion prevention
^ Controls oxidation
^ Eliminates deposits
^ Controls friction
^ Retains anti-foaming properties
^ Superior properties for low temperature operation
FLUID COLOR
Mopar ATF+4(R) is a World Class Fluid having exceptional durability. However, the red dye used in ATF+4°R is not permanent; as the fluid ages it may become darker or appear brown in color. ATF+4(R) also has a unique odor that may change with age. With ATF+4(R) fluid, color and odor are no longer indicators of fluid condition and do not support a fluid change.

If the fluid is changed on a regular basis the ATF +3 will work JUST FINE. Chrysler is just trying to sell more of their dealer only available +4. The aftermarket transmission seminars have not put out any support of this TSB. If it were that critical it would have been covered. I will just have to gracefully disagree with the TSB.
Did you get your car scanned to check the input and or output speed sensors? They go out so much we keep 3 of each in stock at all times. I had one customer quoted 2000.00 for a overhaul, when we scanned it the speed sensors were not showing any input to the pcm. Replaced both sensors, service & flushed the transmission and the car is still driving around with out an overhaul!

Hi:
I have a new yorker 1990, with the same problem. Check the solenoid block(pack), is a block of cables in the side of the transsmition, you see it from the front of the car.
If you open it, you see 3 solenoid an a rubber gasket, lift the gasket, clean the electric terminal of the solenoid with carburator cleaner, after dry cover the electric terminal with silicone for high temp. and install the gasket again.
I hope this help you.
