Will put up a “hello” intro post soon. I’m fairly good with cars. But also fairly new to BMWs. But very new to automatic transmissions (especially old ones). Bought a 1990 325 cabrio for my daughter and I to work on and fix up that will become her first car. It’s kind of a tradition in our family to have old cars for first cars.
Anyway. I’m getting to wrenching and when long story short (when checking TPS) I realized I wasn’t getting wide open with the pedal depressed. Was maybe getting 3/4 tops. Pulled out the trusty Bentley that came in the trunk. First tightened the throttle cable to get rid of that slack. That helped some. Then disconnected the kickdown cable from the throttle body and Loosened the kickdown “switch” (which apparently on these engines is just for tactile feedback) in until full pedal depressing gets me WOT 0.5mm from the stop.
i put the kickdown cable back on the throttle arm and now not WOT again unless I give it a little tug. It’s closer. But not right yet. I’m ASSUMING I need to let out the kickdown cable so WOT gets reached. But reading the Bentley automatic transmission section page 15 it says something about “depressing the accelerator until transmission resistance is felt” and lift the switch up to that point on the kickdown switch.
Seems contradictory or I’m just not that bright. Could really use the help of someone with a bit more knowledge with a bit of a walkthrough here.
Thank you all in advance.
