Possible Transmission Issue Coming?

I'm new here so be nice....:shy2:

I have an '05 quad cab 4x4 with AT and just passed 70k miles. The truck is driven primarily 7 miles each way to work. Almost every morning and every evening (after the truck's been sitting) there will be an ever so slight hesitation when I put the truck in drive -not the engine hesitating but the transmission feels like it's not quite in gear. If I start the truck up and wait to put it in gear while I'm putting my seat belt on and taking off my ID badge and then put it in gear it's fine -no hesitation.

One other thing I'll mention, this winter we actually got a fair amount of snow and so I drove it in 4x4 mode more than I ever had. It seemed to me that this hesitation issued got worse when in 4x mode - happened not just when the truck was cold but when warm as well.

I have no idea on the issue - sticky valves in the AT? Any thoughts would be appreciated.

Regards,

TSB 21-007-06 addrresses an issue with delayed engagement with the 545RFE transmission.

SYMPTOM/CONDITION:
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 also experience a MIL illumination. Investigation may determine that
the MIL is due to one or more of the following Diagnostic Trouble Codes (DTC's):​

P0868 - Line Pressure Low.
This DTC will be the most frequently occurring DTC for
the delayed shift condition.
P0944 - Loss Of Hydraulic Pump Prime.
P0731 - Gear Ratio Error In 1st.
P0736 - Gear Ratio Error In Reverse.
P0841 - LR Pressure Switch Rationality.
P0876 - UD Pressure Switch Rationality.
The delayed engagement and MIL condition (DTC's) may be caused by a suspect
transmission cooler return filter with a part number of 04799662AB. A suspect​

​

cooler return filter may cause the transmission sump filter to split at its
plastic-to-metal crimp. If the transmission sump filter becomes split at the crimp, then one​
or more of the above DTC's may also occur.

Thanks for the reply's and sorry I haven't been back sooner....I'm not showing a CEL or any other kind of light. I haven't had a code check done. It doesn't seem to be getting any worse now that we've begun to hit the heat of summer.

My next job is to replace the shocks - 72k on all of them and haven't been replaced so I figure it's time....

I have the same symptom but it occurred after I let my truck overheat this winter. I guess it messed something up. Im curious, why do the use the same tranny in the 1/2 ton and the 3/4 ton? Something about that makes me think its not near the quality as the 68RFE. Am I wrong?

Is it idling at somewhat higher RPM's? Mine was doing something somewhat similar. I mainly noticed it in reverse though. When I would start the truck up and put it in reverse almost immediately, it would lurch backwards, and the RPM's would drop and it would almost die. And then it'd rev back up and be fine. It was idling around 1400, and would constantly rev up and down between 800-1400 while sitting. Then it started shifting really roughly, and the check engine light came on. Got code P0121, threw a new Throttle Positioning Sensor in there, and no problems whatsoever.

I haven't noticed any idling issues. My truck typically idles around 600-700rpm. I'll pay attention to it. I have had issues with the truck stalling out shortly after starting - usually when I have my first stop of the morning - at a stop sign near my house. I took the throttle body off and cleaned it up and it's not done it since.

Have you serviced the trans before? Maybe at about 35-40k, if not it u need to anyway! Its not to difficult to do it yourself if you have any skills! If you talk to the service manager about your prob. he should want to help you, thats his job. My 08 mega has done this a few times with no mil lamp and as you said but its been about a half a year since. When i worked at a gm dealer i was not a stealer either, but did alway recomend preventative maint. Good luck!

I did have the transmission professionally serviced at 43k. It's not got another 30K on it. I'm pretty handy but have never removed a transmission pan - though it looks relatively easy to get to - just always nervous that I'll not be able to get a good seal on the gasket and mess something up....

Just found this online

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.

Image



The customer may not experience the delayed shift engagement until after the transmission has been serviced, where the cooler return filter was replaced. The condition is not detrimental to the transmission, but may cause concern with the customer.

The repair will require one Mopar P/N 04799662 cooler return filter.
Applicable Vehicles
• 2000 - 2004 (AN) Dakota
• 2002 - 2006 (KJ) Liberty
• 2000 - 2003 (DN) Durango
• 1999 - 2004 (WJ/WG) Grand Cherokee
• 2003 - 2006 (DR) Ram Truck
• 2005 - 2006 (WK/WH) Grand Cherokee
• 2004 - 2006 (HB) Durango
• 2006 (XK) Commander
Repair Procedure
(Review cooler filter replacement and safety procedures in the ALLDATA system before beginning.)
The above condition may be caused by a suspect cooler return filter — 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) is 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: 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.)

Diagnosis:

1. Turn the ignition to the “OFF” position.

2. Raise the vehicle on a suitable lift.

3. Inspect for the transmission build date (Julian date) (Fig. 1). The transmission build date can be determined by inspection of the 20 digit transmission identification number (DDDYxxxxxPpartnumber). The transmission identification number is stamped on the left side (driver side) of the transmission oil pan flange. The first four (4) digits of the transmission identification number are the transmission build date, in Julian date format. An example of a transmission identification number would be:

101510492P52119684AA. The first three digits ( 101 ) of the identification number equal the day of the year, in this case 101 equals April 11. The fourth digit ( 5 ) of the identification number equals the calendar year, in this case 5 equals 2005. So 1015 equals April 11, 2005.

4. Determine if the vehicle's transmission was built on or between one of the two sets of Julian date build ranges listed below:
a. Julian date 0425 (February 11, 2005) to Julian date 0455 (February 15, 2005). 0425 to 0455.
b. Julian date 1015 (April 11, 2005) to Julian date 2345 (August 22, 2005). 1015 to 2345.

5. If the vehicle has the above condition, and if the transmission Julian build date is on or between the range of dates listed above, perform the Repair Procedure.

NOTE: DO NOT use a replacement cooler return filter with a part number of 04799662AB. This filter is suspect of causing the above condition. The filter part number is stenciled on the side of the filter case.

Parts Required:

1 P/N 04799662 Filter, Cooler Return
4 P/N 05013457AA Fluid, Automatic Transmission, MS-9602 ATF+4, Quart
1 P/N 05010884AA Mopar ATF-RTV

Repair Procedure:

NOTE: All cooler return filters with the “AB” suffix (04799662AB) 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).

Sorry about resurrecting and old thread. I thought it was better than posting a new one. I was getting ready to do a tranny fluid change and I stumbled upon this TSB. I have had this problem since I bought my truck in 2005. I brought it to the dealer a few times but I was sent away with a could not reproduce. I'm out of warranty and I don't have a dealer near. I figured I would change both filters when I change the fluid.

The problem is that my Google Fu has not returned any sources to buy the cooler return filter (04799662). Does anyone know where to buy or are their any site sponsors that sell it?

Rock Auto, Ebay, various other online retailers have it. Any Napa, Advance Auto, Autozone, or Oreillys will also have it, and can be ordered from them online. Most places sell it in a kit with the pan gasket, flat filter, and spin on filter. Is your truck a 4wd or 2wd? There is a difference in the flat filters. The 4wd version has a longer pickup to accomodate the deeper 4wd pan. The 2wd version will not work on a 4wd and vice versa.

I never really used the OEM version (except for the change I did a few days ago because the mood struck me and the Dodge house is a block from my house), because Im not a fan of the RTV gasket and all the other kits have gaskets. Im also going to cuss myself in 50,000 miles when its time to scrape that RTV off but, oh well its worth it to be lazy for a day lmao. Even though I always used non OEM Ive never had the drainback problem, if Im not mistaken this was only on certain dealer and wix filters and should have long since been fixed.

I can't thank you enough. I guess my problem was searching only on the part number. It's RWD.
