Re: leaking fluid [djnew] by dustyk

Let me guess. The guy that told you that drives a chevy or a Ford!
 
There is no such "valve" that releases fluid from any Chrysler built transmission onto the ground. Fluid should not be leaking from the transmission for any reason. Next time you're at a Dodge dealer look under every Dodge truck, Dakota or RAM, and see if there's tranny fluid under them. Some of these trucks sit in one spot for weeks or months.
 
I'm assuming this is an automatic transmission. If fluid is leaking from the transmission it is not normal. There are a number of areas of the transmission that have a potential for leaking, including the rear output shaft seal, shift lever pivot shaft, throttle valve pivot shaft, front seal, or the transmission oil pan, just to name a few.
 
If this transmission has been apart by somebody, check to see if there is a transmission pan gasket installed. A gasket is not used by Chrysler on automatic transmission pans because they eventually leak. Chrysler uses RTV sealant from the factory and that's what I use. Mine or any I've done have never leaked. (Chrysler part number 05010884AA.)
 
Most aftermarket transmission fluid filters include a gasket. Most of these that I've seen are compressed cork and rubber composition. Cork swells and eventually displaces the rubber component, rendering small voids that absorb fluid causing the ATF to wick out. Also, when a gasket is used the oil pan bolts will have a tendency to loosen over time because you cannot properly torque the pan bolts down without overtightening the gasket and crushing the material. This can accelerate a leak.

Dusty

If you have a Dakota (or a Jeep or RAM, for that matter) with a 4.7 engine, you also have the 545RFE automatic transmission. This transmission has a reputation for being exceptionally reliable and trouble free. The only cause I've seen or heard of that causes delayed engagement is a defective Cooler Return Filter. There was an approximate four month period of time that Cooler Return Filters were defective from the component manufacturer. This is covered in Chrysler Technical Service Bulletin 21-015-05 as follows:
 
"The customer may experience an initial delayed shift engagement following an extended off (not running) period of time, generally after being parked overnight.The initial shift engagement may feel like a delay or slip when a transmission gear (reverse or drive) is first selected after engine start.
 
The customer may not have experienced the delayed shift engagement until after the transmission has been serviced, where the cooler return filter was replaced during the service and/or repair.
 
The condition is not detrimental to the transmission but may cause concern with the customer. The above condition may be caused by a suspect cooler return filter a part number of 04799662AB. This “AB” suffix / level filter may allow transmission fluid to drain back out of the torque converter. The drain back condition may occur over a period time when the engine (and transmission) are not running. With less fluid in the torque converter a delay in gear engagement may occur at engine start up while the torque converter fills to its proper fluid level.
 
All 04799662AB cooler return filters with the “AB” suffix are suspect. The above condition may be corrected by replacing a suspect “AB” filter with a new cooler return filter whose part number is 04799662 (with no suffix or with a suffix that is other than the “AB” level).
 
NOTE: The cooler return filter, p/n 04799662, will not be available until September 09, 2005. The filter part number is stenciled on the side of the filter
case.

 
NOTE: A replacement 04799662 cooler return filter may come packaged with a
separate threaded adapter stud. The threaded adapter stud is used to attach the cooler return filter to the transmission. Inspect the stud and note end without threads. Install the stud end without the threads into the cooler return filter and tighten the stud-to-filter connection to 18.6 Nm (165 in. lbs.). Once the threaded adapter stud has been installed to the cooler return filter, install the assembled cooler return filter to the transmission and tighten the filter to 14.1 Nm (125 in. lbs.)."

Dusty

97 Dodge Dakota Transmission Concern by terrimw
Sep 26, 2008 (1:08 pm)

We are looking to purchase a 96 Dodge Dakota V6 Transmission for our son. One owner, very clean, low mileage. Unable to talk to the previous owner (has passed away) but did speak to his son who said there were no problems that he was aware of but admitted to limited knowledge.
The check engine light is on and it's sending a code of 1762. The code indicates three possibilities and all three have been checked/changed. First they replaced the PCM, then they ran a pressure test which came back normal and finally replaced the governor sensor. The light is still on.
Does anyone have any ideas of what this might be? I don't want to buy the truck even though we're getting a really good deal if we're buying a big bunch of trouble. All input would be greatly appreciated! Thanks!

I looked up the code 1762 and it came back as "The Governor Pressure Sensor input was too high or too low for 3 consecutive park/neutral calibrations."
 
This is a TRANSMISSION code... not the engine. It sure sounds to me as if somone has been "shotgunning" the problem by blindly replacing parts.
 
If it were me, I would first replace the xmission fluid (and all filters) to ensure it has only the Dodge-specified fluid in it. (Using Dexron (GM) fluid is known to cause problems in Dodge xmissions.)
 
Of course... to replace the "governor pressure solenoid and sensor (transducer)." the filter and fluid should have also been changed.
 
If that does not help.. then a transmission-shop that has the equipment to read the datastream while driving should be able to isolate the trouble.

Exactly how many miles are on this vehicle?
 
Has this vehicle sat for a prolonged period, or had infrequent use?
 
How does it Drive? How are the shifts?
 
How is the park-to-drive or nuetral-to-drive engagement? Is it harse?

Dusty

not good cold by first_truck

Hi... I just bought a 2000 Dodge Dakota Sport. 105000 miles, 3.9L magnum, automatic transmission. I got too good of a deal on it even if it needs a tranny rebuild. When the truck is cold it does not shift into second without with RPM's hitting 4000. It is almost as if it will not shift into overdrive. It is not consistent when it does this. The check engine light is not on. After driving about 10 minutes it starts shifting normally and drives great. I have checked all fluids and they are good. The guy I got if from put some Lucus transmission "stuff" in it and really no change. I have found no leaks. I have done some research but want some more opinions. Govenor Pressure Solenoid?? or Speed Sensors?? In low and High Gear (1 and 2) truck runs and shifts fine.
Thanks, first_truck

A binding or loose Throttle Position Cable can cause this, or a weak or missing Throttle Return Spring.
 
I highly recommend that you get that Lucas stuff out of there. Mopar automatics use a special ATF (ATF+4) that can be easily destabilized by incorrect or incompatible fluids.

2003 transmission question by tonym5
Sep 29, 2008 (5:31 am)
Reply
I have a 2003 quad cab with auto transmission. If I depress the throttle hard in order to pass or climb a hill the transmission seems to go into nuetral and the engine rpms peg. When I release the throttle, the transmission goes back into gear. Is this some type of safety feature or is there a problem?
Thanks in advance for your help.
Tony
