yo!
eziest and cheapest cks first for you;
Modulator - is #1 problem
You have a modulator on the passenger's side of the vehicle pointing towards the driver's door. Pull the rubber line off the modulator and see it trans fluid comes out of the line, if it does your modulator is no good. It can cause any of the above symptoms. If good, check vacuum line from engine to mod valve; or kinked/cut vacuum line to modulator; Check vacuum at modulator - should be 18 - 20 "
Check the kickdown cable; it is self-adjusting over a tolerance range of 1 in. (25mm). If the cable requires readjustment, reset the by depressing the semi-circular metal tab on the self-adjuster mechanism and pulling the cable forward (toward the front of the vehicle) to the "Zero'' position setting. The cable will then automatically readjust to the proper length when kicked down
& the 2 prong plug is for the torque converter's lock-up solenoid. In mid 88 the tranny had a second solenoid for 3rd to 4th inhibit; do you have a 2 prong on tranny or is it on the harness?
an early A4LD some had a mechanically locking torque converter, but later ones have an electronic one, however, this doesn't effect the normal running of the box if not connected; 3 - 4 shift and lock-up are commanded by the computer - these two solenoids can set codes - one wire is red, other is tan/light blue in 2.9 engine or yellow in 2.3
& converter clutch solenoid wires are Red; and white for 2.9 or org/yel for 2.3
Governor stuck or sticking is a very common problem. The governor is inside the tailshaft and requires removing the driveshaft and the tailshaft to access it (on a 4X2). 4X4 requires dropping the t-case as well. They do stick, but its usually from dirty fluid
"Look in the rear where the governor hub goes, and look for wear grooves in the case. If no wear is noted, use the rubber square cut seal rings for the governor. If wear is noted, stick with the steel rings. I usually take some fine emmory cloth and polish the bore to lessen the wear. Next area for inspection is the governor itself. Make sure the valves in the governor assembly move freely, they cannot stick even a little, unless you like torture. If they stick, clean them and polish the valves with fine polishing cloth..

Good Luck to you!
