Re: 1997 transmission sensors
To start off, I would get a spray contact cleaner and clean the contacts
on the TPS which controls the transmission shift points. These throttle
position sensors on the 4.0's are notorious for getting bad connections.
Same goes for the other computer sensors like the one on the
transmission, they are easily prone to corrosion and intermittent
failures because of it because they only pass low power computer
signals. Using a spray contact cleaner that the electronic stores sell
does them wonders. Coating the plug seals with dielectric grease also
helps keep them clean.
When electronic parts fail, they normally up and die. Bad connections
usually make the intermittent failures.
I would do the clean before spending money on parts.

Re: 1997 transmission sensors
Thank you so much for your time, Mike.
Are there any diagrams on-line that would show me the sensors
locations, or should I go ahead and buy the manuals they have for my
model at an auto parts store? What particular transmission do you think
I have?

Re: 1997 transmission sensors
Thank you so much for your time, Mike.
Are there any diagrams on-line that would show me the sensors
locations, or should I go ahead and buy the manuals they have for my
model at an auto parts store? What particular transmission do you think
I have?

Re: 1997 transmission sensors
I would get a basic Haynes manual for it. They aren't great but they do
help locate parts and give you all the settings for installing things.
The factory manual is the best, but it is expensive. I guess it depends
on how many repairs you are up for.

Re: 1997 transmission sensors

The factory manual is the best, but it is expensive. I guess it depends
on how many repairs you are up for.
