What are you talking about auto shift control solenoid ? Which transmission does yours have ?

2-3 Shift Solenoid Valve

Is there a DTC - diagnostic trouble code stored ? Which gear or gears are not working ?

is it a linkage issue? if the shift lever is working and you can feel the detents, check your fluid make sure it is full and clean, if not you could have internal issues with the trans

The transaxle Control Module (TCM) monitors the malfunction of sensors and actuators relating to transaxle control. When the TCM detects a malfunction with the control, a signal is send to the Engine Control Module (ECM) to trigger the Engine Light or Service Engine Soon light. The ECM stores the P0700 code and it means the TCM detected a malfunction with the transaxle controls.

most auto trans don't shift into reverse when low. Reverse takes the most fluid of all the gears.
Check for a bad shift solenoid or wires to and from that circuit. Most trans-axles have them now.

P1886....Transaxle Shift, Timing Solenoid performance

You will need to check your timing gear and see if it is worn out. You will have to replace the timing cover gasket and a new timing chain.

18 = Cam Crank Problem
36 = Transaxle Shift Problem

Hope this helps. - Jarett

The transaxle shift problem I am unfamiliar with, but the cam crank problem is probably either your Camshaft Position sensor, or Crankshaft Position Sensor.

This is a case of pure coincidence. It just went bad at the same time you made the repair. Just a fluke,no worries.

   • Transaxle
     

To install:

NOTE Use new circlips, split pins and self-locking fasteners for assembly.

1. Position the transaxle to the engine and tighten the flange bolts to the following specifications:
   
   • M8 bolts: 72–84 inch lbs. (8–10 Nm).

2. Install or connect the following:
   
   • Transaxle mount and torque the bolts to 65–80 ft. lbs. (90–110 Nm)
     
   • Flywheel cover and torque the bolts to 72–84 inch lbs. (8–10 Nm)
     
   • Axle halfshafts
     
   • Starter motor
     
   • Shift cables
     
   • Speedometer cable
     
   • Clutch slave cylinder

They had a problem with this plastic washer that is in the shifter tower it sits just under the shifter it self and gets worn out and causes this to happen- hope that helps.
