A25C Transmission going to neutral after taking foward or reverse

A25C goes into gear. after operating 10 to 15 minutes will drop forward or reverse and go to neutral. throws code 432 (problem with wiring or solenoid ZM2 F-clutch). performed ohm test on wiring harness starting at ECM. ohm value out of spec for ZM2 solenoid. Values would be high when machine is hot and will below spec when machine is cold. felt like problem was solenoid. replaced, still same problem. about to start pulling wiring harness. does anyone have solenoid location diagram and suggestions before I snatch wiring out

    Make, model and serial number would be a good first place to start. With your description one can only guess that you are working on a Volvo truck.

    take a look at the pdf, that is the location of the (F) solenoid. suggestion, check where the loom pass's through and out the back of the cab, it often rub's there.
