Trans light on out of blue, had low gear power only. Tried to accelerate and would not exceed 30 mph. Sat vehicle for several months, recharged battery and trans light has gone off with full use of trans. Not sure if this is a trans problem or something different. How do I identify problem? Was going to take to trans repair, now not sure where to take it.

Hello, was it wet outside, raining, you just washed the car when this happened? It sounds like the transmission went into "Limp Home Mode" . They put a service bulletin out on this in 1995. Does this help? I would first do this repair and, if you can remember if the car was wet etc like I ask before, this may be your problem.

44-24

DATE: 1/95

MODEL: Sedan Range (4.0L) up to 93 MY

SUBJECT:
Automatic Transmission - Defaults To "Limp Home" in Wet Weather - Repair Procedure

ISSUE:

The Transmission Failure malfunction indicator lamp (MIL) illuminates and the transmission defaults to the "Limp Home" mode during rain or after using a car wash.

Water can enter the vehicle through the engine management harness grommet in the vacuum tank under the battery tray. The water can drip onto the Transmission Control Module (TCM) causing it to illuminate the transmission MIL and default to the "Limp Home" mode.

ACTION:

If 4.0L Sedan Range vehicles up to 1993 MY (VIN 667829) illuminate the transmission MIL and default to "Limp Home" mode during rainy weather or after using a car wash, seal the EMS harness grommet as described below.

1. Record the preset radio stations (including X-mem) and remove the battery from the vehicle.
2. Remove the battery tray, disconnect the EMS harness from the vacuum tank and remove the vacuum tank

3. Inject a liberal amount of Bostik Alpha Seal 132 or an equivalent sealant into the areas shown in Illustration 1.

A. - Around the vacuum tank inner recess for the grommet
B. - Around the EMS harness at the front and back of the grommet
C. - Between the EMS harness grommet and the body panel face

4. Replace the vacuum tank and press down firmly to squeeze the sealant around all of the joints
5. Clip the EMS harness into place.
6. Reassemble the battery tray before the sealant sets. Torque the mounting bolts to 12 - 16 lb ft (15.5 to 20.5 Nm).
7. Install the battery, code the radio, and reset the radio stations and clock
