UPDATE now it is intermittently stalling when I shift into drive. The idle drops as soon as it hits D and stalls. Someone has to have had this problem before!!



PLEASE HELP!!

I have been working on my deck all day so please forgive me if I leave anything out.


Last week I was driving on the parkway and my car felt like it kicked out of gear and then the "check engine" light came on. I didn't notice anything else.

I got off the parkway and onto the slower speed roads and headed to Autozone to have the code read. It came up at P0755 (Shift Solenoid B) but obviously as we all know, that doesn't necessarily mean the solenoid is bad. After doing quite a bit of research online for people with similar issues (there are a lot of them), I started from the bottom and replaced a random 10A fuse (ignition sw) under the hood. Check engine light immediately went off and car was running/shifting fine. I decided to hop on the parkway again and see if the problem appeared again and after about 5 minutes it kicked out of gear again and the light came back on. The car doesn't only stay below 3rd (1st/2nd/R) though, and works fine intermittently but the light stays on. I tried changing the fuse again and same deal. Replacing the fuse fixes it temporarily but obviously that isn't fixing the problem.

I know it has to be a short of some kind (between the fuse box & TCM or TCM & tranny). I have more details if anyone needs them but I have done so much research!! I have found a Haynes Manual, Service Manuals, wiring diagrams, personal accounts/directions, etc. free online.

I have tools and a multi-meter. I have car ramps if needed and know how to unhook the negative battery terminal...

Can someone please tell me exactly what to do? I am overwhelmed & my brain has turned to mush....




PLEASE HELP!

Thanks in advance!!!

 

Can anyone help? or at least direct me to a good tutorial on which wires to check?


Thanks!

 

Here is a PDF file that we use at the dealership. I did get you pm and will send you a message too. This also goes for everyone else. If you haven't gotten a response for a few days, send me a message. I do moderate other sections.

Symptom:
P0755-2-4 SOLENOID CIRCUIT
When Monitored and Set Condition:
P0755-2-4 SOLENOID CIRCUIT
When Monitored: Ignition key is turned from the OFF to RUN position and/or key is
turned from the CRANK to the RUN position, then every 10 secs thereafter, or when a
speed ratio or pressure switch error occurs. All 4 solenoids are tested for continuity
continuously.
Set Condition: If a solenoid is On, power is momentarily interrupted, then reenergized. If
solenoid is Off, power is momentarily energized, then deenergized. If an inductive spike is
not sensed by the TCM, it is retested. If the solenoid fails 4 times the code sets.
