Alternator started over charging to 17 volts and I had to have it replaced. Now the Transmission Temperature gauge does not work. I think the Mobile repair guy may have knocked the wire off while he was under the motorhome. Does anyone have any idea where the wire might be located on the transmission? He also had to replace the turbo boost boot while he was under there. I did discover that without a turbo, the top speed is 45 mph and it takes a long time to get up to that speed.
