My Dad has an 1988 Isuzu Trooper 2 automatic. There seems to be some trouble with the transmission computer because it won't shift except manualy and the overdrive doesn't shut off. My Dad is a mechanic and he thinks it might be a computer problem, but he doesn't know for sure. I was wondering if anyone had a similar problem and knew where to get the proper part. Thanks in advance for any help.

So... I just bought this 1988 Isuzu Trooper II and its good but when I drive in order for it to shift at all I have to get to between 4-5 thousand RPM. Anyone know whats wrong? Checked the transmission fluid and its fine.

i just paid 8 hundred for this trooper II 88 46ZE1. automatic tranny

acts like a manual and when it does shift its at high rpms when

it does.only fires on three of the four cylinders.#4 cyl doesnt

burn hot when being tested with a heat thermometer.oil, temp and

fuel gauges dont work, cost me another 219 to give tranny a

tune up and filter. New spark plug wires roter, cap new bosch 4

prong spark plugs oil change oil filter and air filter made no

diferrence.so i think i just joined your club.
