I wondering if anyone can tell me anything about the Service Reference Booklets that were produced in the 50's and given the mechanics working for Chrysler at that time. I have a number of these from my grandfather who was a Chrysler Mechanic. They vary from Mint condition to a number of them that have stains in the lower corner. Any info would be appreciated. I saw a few of them on Ebay ranging from $15-17. I have a few hundred of them.

 

Hi the rpm do go up, in 1st and reverse but is its locked in 2nd it wont go any higher.
Where is the sensor located.
Does the mechanic need strip gear box as suggested to locate transmission oil switch or sensor.
