Yo Done0812Bar,
Try a Self Test for Diagnostic Trouble Codes (DTC)s by my pal, BroncoJoe19

Some basics;
The engine temperature must be greater than 50° F for the Key On Engine Off (KOEO) Self-Test and greater than 180° F for the Key On Engine Running (KOER) Self-Test.
Run it around to heat the engine up and shift thru all gears including Reverse.
Make sure A/C is off and transmission is in Park (automatic); or in Neutral for a Manual & release clutch.
Then turn off engine, all accessories/lights (close driver's door) , etc.
Do KOEO test First
Post Code(s) here according to:
KOEO
&
KOER
We are looking for a code such as DTC 634; "E4OD Nagging Neutral Nonsense & Pinpoint Test, Manual Manual Lever Position (MLPS) also called Transmission Range (TR) Sensor. Some of the problems the MLPS can cause are wrong gear starts, TCC hunting, no 4th gear, engine stalling, high or erratic line pressure & a sudden neutral condition; The negative lead of the multimeter should be placed at the MLPS signal-return ground terminal at the MLPS...This sensor is responsible for more malfunctions than any other sensor in the sys- tem, and the kicker is that it seldom stores a code 634..."

Or without a code, Water Intrusion of Manual Lever Position/Transmission Range (MLP/TR) Sensor TSB 95-2-12 for 89-94; Some vehicles may exhibit a shift concern and/or a harsh engagement concern due to water intrusion into the MLP/TR sensor and vehicle harness. There may also be a number of different DTC's along with those concerns.
Replace the MLP/TR sensor and vehicle harness connector if signs of water penetration are evident. MLPS IS ON DRIVER SIDE OF TRANSMISSION.
Is the Transmission Control Indicator Light (TCIL) blinking while driving? It is also ref to as the OD on/off LED/Switch @ end of tranny gear stalk.
