I recently installed an AW71L transmission from the PNP into my 89 740 non-turbo. It worked well until the car started slipping out of 3rd gear on the highway. Consulting the FAQ, my son had the tranny filter changed and fluid replaced.Works on highway OK. Now it is having a hard time shifting up to second from first (but only when the car is cold right after startup, when warmed up, shifts great). I have adjusted the kickdown cable but still not shifting. I suspect the plastic balls in the pressure valve are worn out. I plan to replace them according to the FAQ directions, but am wondering if the following Green Manual is the correct one to use:
"Automatic Transmissions : BW55 AW55 AW70 AW71 Engines
Repairs and Maintenance Service Manual
Section 4 - Group 43"
It is for sale on eBay.
Thanks for any help.
