Hi All,
Fist off, it's great to see this site is still "bucking". I joined close to 12 years ago as a teenager when I bought my 95 (unfortunately I lost my original email).
It's nice to see familiar users like Miesk still providing a wealth of knowledge.
That being said, here's what has me stumped:
I'm dealing with a loss of overdrive among other things.
After I had my E4OD rebuilt it starting leaving OD engaged at idle and would subsequently **** the engine (after warm-up). I took it back to the shop and they "fixed" it by clipping the purple/yellow wire by the computer. I ended up wanting to fix things myself after losing confidence in the shop.
I found the solenoid connector harness had rotted so I soldered in a new one and installed a new solenoid pack when I changed my AT filter. I also replaced the MLPS and soldered in a new harness for it (followed the proper alignment guidelines). Overdrive would still not engage so I ran a switch inside the cab and verified the TC locks up. I am temporarily using the switch to prevent overheating. There is continuity from the pcm pin to the connector pin on the tranny.
Here are my other symptoms:
overdrive light is not blinking (button is still functional)
rough putting into gear
rough shifting or shifting from 1-2 entirely too quickly causing acceleration problems.
WILL NOT SHIFT FROM 1-2 MANUALLY
no cruise control
abs light
speedometer bounces at 70+ (overdrive worked before so I wouldn't think this is an issue).
If I reset the computer it will shift smoother but will not engage OD. Also, on cold-starts it will rev extremely high and then almost die, or I have to feather the pedal to get it to start. After the engine is warm this is not an issue. I also replaced the TPS at some point and verified the voltage but I will recheck this after work.
Best,
AL
