Testing Governor Pressure

How to test Governor Pressure on an Automatic Transmission. I'm using a Chrysler 42RE in a 1997 Dodge Dakota. What I do can be applied to any automatic transmission with an Electronic Governor.

200-R4 Governor and accumulator spring
The project continues to refine so to speak the overdrive 200-R4 transmission retrofitted to a 1972 Oldsmobile Vista Cruiser. Cleanliness and patience, and being flexible too when working in cramped conditions helps with these sort of projects. The softer shift (will still be more firm then stock, as there is a shift kit in this transmission) will not be detrimental to the 2nd band as it is a Kevlar one, and there is a large oil cooler fitted to the transmission lines as well. The dust cover for the torque converter will finally be fitted too when all is said and done.

Dodge Durango Transmission overdrive problem
This is a 1998 Dodge Durango that the transmission was acting up when ever you would go 60 mph and above. The symptoms were; transmission would not stay in overdrive which caused a jerking motion on the vehicle because it was going in and out of gear when the vehicle would reach the speed of 60 mph and above. Had terrible jerking motions at speeds of 70 mph and above and tachometer would constantly be jumping due to overdrive dropping to third and back to overdrive. The vehicle was road tested by a former Dodge repair technician who has his own repair center now , he scanned the vehicle while the symptoms were happening, nothing was showing on the scanner that there was any problems, he said it was a transmission problem and suggested I take to a transmission repair center. The transmission repair center technician ran his scanner while the problem was occurring, all it showed was the Durango computer telling the transmission to drop down to third and back to overdrive. There was no indication why the computer was telling the transmission to do this, no codes in the computer at all and no indications of problems on the scanner. Transmission needed to be serviced so while at the transmission repair shop they recommended replacing the governor pressure solenoid and transducers sensor and said that this could cause the problem but was not 100% sure. So they serviced the transmission and replaced those parts and it still had the same symptoms. So I did a Google search on this problem and found out that there is several things that could cause the symptom or similar symptoms. One thing that came up on Google most of the time that repaired the problem was the throttle position sensor, I replace this part and symptoms continued. Second in line that would fix this problem for others that were having similar symptoms was replacing the output speed sensor which is on the outside of the transmission, I replace this part and it fixed my problem. I would suggest if you are having this same problem to start by replacing the output speed sensor or throttle position sensor before replacing the governor pressure solenoid and the transducers sensor. I am not a professional mechanic but I do repair my own vehicles most of the time and have been doing it since 1977 so I do have knowledge repairing without having to go do a Google search. I hope this will help anyone else that is having the symptom.





Cummins 48re Automatic Transmission 1 to 2 Shift Problems Test Drive
I'm test driving my truck varifying the 1 to 2 shuttle shift problem. All Dodge 2500, 3500 48re automatic transmissions exhibit these symptoms after about 50,000 miles. Watch my other videos of the 48re tranny, including the updated solenoids, and instillation video of the new solenoids to correct this shift problem.

Craig and Danny attempt to install a new governor pressure sensor into a 1997 Jeep Grand Cherokee Laredo. Hilarity ensues as the due ponder why transmission fluid looks like something out of a slasher film, whether Lee Iaccoca is still dead, and why you can never trust the guy behind the parts counter at the Chrysler dealership.

700R4 Torqe Converter Lock Up Wiring
I've learned a lot over the winter rebuilding my Chevy automatic transmissions. Thanks a bunch to Michelle for letting me take over the basement all winter and putting up with the musk of burnt tranny fluid. I feel much better about my automatic Astro van now, knowing I can fix the transmission, should I burn it out. Before it was like "when's this trans going to go?" and I would always be on the look out for a new van, or have a back up truck ready to go. Now I will have a back up automatic transmission built and ready to install. I didn't really film the rebuilding, cause honestly I didn't know what I was doing, and it took about 6 months, hour here, hour there. Next one I will film, with short cuts, to show what you most likely get with a $800 rebuild. I did a few mods to the automatic transmission to make it hold up better towing the 4500lb electrical trailer. Those mods are going to cost me more work on the install, because I will have to mess about pulling the governor, and modifying the governor, to get the shift rpms back to where they were before the higher pressures and bigger valves. I have 2 videos covering the mods I did here.
