2002 FOCUS CODE P0750 Shift Solenoid A Malfunction
Hi I'm having problems with the transmission after third shift it jumps into neutral for like five seconds then jumps hard into fourth, I purchased a OBDll CAN scaner and it read P0750 Shift Solenoid A Malfunction I cleared the code and the car ran perfect for like two days and started all over with the same code, how hard is it to replace this solenoid and witch one is it in the transmission box and do you think this will take care the problem, I went to the ford dealer and one solenoid cost $100 not bad but it shows 3 in the transmission witch one is it?, I know if I take it to a transmission shop they just want to replace the transmission to make more money, I'm a aircraft mechanic and I think I can do this but I need more information from someone thats been thru this problem before, thank you in advance for your help.

UPDATE 8/9/2007: Now the code won't clear & the engine light resets off and comes back up within 2 minutes (It's getting worst HELP)

An oil catch pan/Filter and 4 quarts of oil. and some rags.

Pull pan. 20 screws. SPLASH
Unplug temp sensor from filter. Plug sensor in new filter. (just pulls out)
Pull Down filter. Has oring squeeze is all. She comes out with a tug.
Unplug "a"
5/16 on solenoid.
Tug on solenoid. She slides out.
Oil up orings on new solenoid and pop back in.
Plug wire back in.
install filter
reinstall pan with gasket that came with filter.
Torque bolts to 60-70 inch pounds.
Dump in 3 quarts.

Solenoid A
Thank you to everyone for the great information. My OBD reader was saying Solenoid A. Followed the other posters instructions and have no problems again. Most of the shops wanted 2 hours labour. I did it in about 2 hours myself. My 02 Focus has 261k kms. Still going strong. Also did the Thermostat Housing recently.
