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.
The Idiots' Garage: Jeep Transmission Part 1
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
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.
Overdrive Transmission - How to test the Wiring
There are 3 or 4 switches in the wiring to get your overdrive to engage. If
any one of those has failed your overdrive won't engage. In this video we
will run you through the steps to test the wiring going to your overdrive.
Transmission Solenoid Testing (Ohms Law) - Transmission Repair
Transmission Solenoid Testing. Here I use Ohms Law for testing. I believe
that this is the only way to test your solenoids on or off the vehicle.
Remember that the solenoids fail under LOAD! So just Ohm testing on its own
is not really accurate. Other tests can be done, but if you just own a
VoltOhmeter, that should be all you would need to perform your testing.
Voltage drop testing is also accurate but you also need to put your
component under load.
Ohms Law, Learn it, make it your own.
Voltage Divided by Ohms equals Amps...
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.
