only have a oil pressure gauge and engine temp besides the basics, engine only moves when towing alot up a certain hill
would the ford dealer have recommended a gauge put on an E40d
No OBS came with a factory trans temp gauge. Ford did that in late '02 or '03 and now all Ford diesel have them as far as I know.
The trans temp is just like the EGT it keeps you aware of how things are going or if you are starting to have problems. Some say EGT first then trans, for others it's the opposite but both are important.
The E4OD has a port on the side IIRC that the temp probe can screw into. Do a search there was a thread with pics on it somewhere in here.
