THANKS A HEAD OF TIME
How's the fluid look?
Regards,
Dusty
Thanks,
Bobby918
If this with the maximum load the temperature of 160-190F is actually very good at 1700 RPM.
Now the 20,000 CGVW seems above a '98 3/4 ton chassis limit and could explain the high temperatures on hills.
Does the engine temperature also climb? If it does the radiator might not be flowing well (partially clogged) or the radiator might not be expelling heat fast enough under load from lose or corroded cooling fins. It could be that the coolant temperature is overheating the ATF.
As far as the tranny goes, over tightened bands can cause this on the Mopar "RE" series, among other things.
Lastly, I hope AAMCO used ATF+4 or at least ATF+3. Dexron-Mercon or Dexron-Mercon with a friction modifier additive will cause Mopar trannys to run considerably hotter. A lot of transmissions shops will use Dexron with an additive because its a lot cheaper than ATF+3 or 4. But it won't work right.

The ATS looks nice but themag-hytec looks like it has more cooling fins. I like ATS cooling system but Derale also has one. Any comments? I am going to change the fluid when I change the pan
I have a 2001 1500 with a 46re transmission that works fine when "cold". After about 6 miles it won't downshift into first gear when I stop. All other shifts go smooth and it will go into first if I manually shift to low. The governor pressure at 0 mph in drive is 0 psi when cold and goes to 7 psi when warmed up and malfunctioning. Governor pressure sensor signal (b29 on pcm)when cold was .37 volts. Ground control to governor pressure solenoid (b8 on pcm) when cold was 9.27 volts. All these test were in drive at 0 mph. The pressure dropped back to 0 psi if reverse or park was selected. When put back in drive, 2, or 1 the pressure goes back up IF the transmission is warm. The only reference voltages I have are for a 42re so if anyone can help me out with the voltages from the pcm to transmission for a 46re it would be greatly appreciated or of course anyone who knows what the problem is please feel free to jump in.
Thanks,
Wolfer
What is the line pressure?
What have you done so far?
What was the original symptom/problem?
Regards,
Dusty
Possible causes could be:
*1-2 Shift Valve binding or stuck (worn bore)
*Shuttle Valve binding or stuck (worn bore)
*Limit Valve or Limit Valve Cover leaking
*2-3 Throttle Plug leaking
*Worn bore at 2-3 Shift Valve
*Defective shift solenoids
*Test all circuits to the shift pack
*Valve body clogged
*Warped valve body
*Leaky governor plugs or governor plug cover.
Bests,

and it is missing a mounting bracket thing for the transmission... I think it is causing harm, and adding stress to it, I dont know what it is called- so im not sure how to order it....
Thanks- I really need it fixed soon-
First, it is always much more helpful when you're seeking advice or information to include the year, model, engine, transmission, 2-wheel drive or 4x4, mileage, etc., information of the vehicle. I'm really unsure of the item your trying to describe.
If you have an idea of what is missing and where it goes, I would recommend that you go to a Dodge dealer. At this point they are the best bet for helping you.
Good luck and best regards,
Dusty
If you are absolutely sure that you got everything back together correctly, I'm now suspicious that you have an electrical problem or a defective PCM or TCM.
*Make sure all of the valves are installed correctly.
*There are seven check balls in the upper throttle body housing, one of them is considerably larger. Are they installed and installed correctly.
*There is a 3/16 check ball in the lower housing. Measure it. You may have switched it with the one large ball from the upper housing.
*Did you reuse the old separator plate?
Did you have a service manual or some instructions when you tore the throttlebody apart?

Dusty

I work at an Atlanta area Chrysler, Jeep, Dodge dealer. And oh yeah, I've been rebuilding their transmissions for the last 10 years. Chrysler trannys have been very, very good to me!

The transmission has 98,000 miles on it. When I changed the oil it was a little dark, but not for 98,000 miles I suppose. There was very light fuzz on the magnet and no metal of any size anywhere in the pan. The transmission has been malfunctioning for about 2 months now. I just manually shift into first anytime I stop and all is good. Line pressure is 56 psi(0 throttle) to 92 psi (tv wide open). 7 psi at 0 mph in drive is not normal I know. I'm thinking governor pressure sensor, governor pressure solenoid, or PCM. If anyone has the proper voltages for the sensor and solenoid to the PCM it would sure help me isolate the problem. The only reference voltages I have are for a 42RE.
Thanks, Wolfer
Thank you in advance for any help you can provide. I have a 1995 Dodge Ram with a 360 and an automatic.
Two separate issues affect it:
1. Last time I changed the fluid and filter, I found a wedge-shaped piece of metal laying in the pan. It had a notch on one end. Can anyone tell me what this is, and how missing it will affect the transmission?
2. Recently, the transmission would not shift from first to second. I was told that the throttle position sensor may be faulty. After removing the throttle position cable from the linkage on the throttle body, the transmission would shift through all of the gears.
Thank you again for any insights you can provide. ~Joel (abboq1)

I drove 30 miles today and just made it home.
Any Ideas. I just bought it a week ago.
How many miles?
What is the transmission maintenance and service history?
Regards,
Dusty

*Low fluid level
*Partially clogged transmission filter.
*Partially clogged or defective Drain Back Valve (check cooling lines for sludge build up).
* Gear shift cable loose, binding or misadjusted (check operation in first gear selection. If no problem this is a likely cause).
*Burnt or badly worn rear clutch.
*Valve body malfunction: sticking valves, worn bores, excessively dirty. Bad electrical connections to Shift Solenoids.
*Worn or damaged Input Shaft Seal Rings
*Broken Overrunning Clutch.
*Broken Front Planetary Gearset
Best regards,
Dusty
Where is the brain back valve. It does have a cooler in front of the radiator.
Thanks for the help.
I know Ford transmission but do not know anything on the Dodge's

The problem
Transmission will not shift out of 1st. MIL Code 37 comes up and the Transmission Shop is saying a P 0740 code is the only fault code present. Both codes lead to torque converter not locking.
The history
Truck has lived it’s last four years as the third vehicle and only gets about 3K per year (I love the MPG on the motorcycle). Transmission has been service twice in its life and was nearing (or past) service #3. In the past year or so (probably longer) I notice the hose leading to the trans cooler was seeping. My just “watch the fluid level” approach did allow the fluid level to get low a few times but was topped off at the first sign of slipping. Recently the truck saw a bit more action and was called up for towing duty. Towed a car on a u-Haul trailer about 100 miles. About half way home I noticed the O/D automatically cut off (I understand it does this when the temp gets high). Slowed down for the rest of the trip with no hard accelerations. O/D came back on about 15 miles later. No more problems until I reached my destination and dropped car off. When leaving to return the trailer I noticed the tans slipping a bit. Took it easy and dropped off the trailer. When leaving u-haul, trans was slipping bad and anything over 25 mph was impossible. Milked it the 2 miles home. Checked fluid level and it was OK but smelled slightly burnt. Seeing if $20 and an hours time could fix it I dropped the pan and changed the filter. Slight build up of sludge on the bottom of the pan and the fluid had suspended brass particles. Put everything back together and topped off the fluid. Trans is not slipping any longer but it won’t shift out of 1st.
The fix?
Based on the lack of fault codes that make sense, the shop recommends a rebuild in the range of $1,400 to $2,500. Before I give the go ahead I’m doing my due diligence to make sure it’s not a simple problem and the shop is just not trying to rip me off.
Is the trans toast or are there any simple items to check before a full rebuild is authorized.
Thanks

I'm not a mechanic, or a Cummins guru. But I do own an 06 3500 with the CID. I stop by my dealer from time to time to shoot the breeze. About a month ago I was in asking him about the 07's. He said the one problem they have had was a flash update needed to be done with regard to a "particulate burn frequency" with the new Cat-back emission control stuff on the new ones. He said they would begin dropping mileage at first (sound familiar) and some guys even had to have them towed in as they would stop running altogther. He said those were the guys who left them idling for long periods of time which clogged the cat-back. He said getting on it real good here and there has help some of them too. If you haven't visited your dealer for a flash update, it might be worth the inquiry. Good luck...Titanium29
I see I'm not alone with my trans. issues. I've got a 2001 5.9 Dodge Ram 1500 4x4, 113k on it. Bought it used at 92k, no service history prior to that. Appears all stock, no perf. mods. or oversized tires. Trans. was fine when I purchased, began to start in 2nd after a stop around 105k. Would be fine if I manually downshifted to 1st, which I did for a while. Very occasionally would go down to 1st on it's own. Eventually began to shift down to 1st more frequently (maybe 20%) always followed by a delayed 1-2 shift @ approx. 2800 rpm. Seemed more likely to hit 1st when cold-could always count on it when leaving home in the AM, again with a late 1-2 shift. Somewhere around this time, the pan actually ROTTED out (on a 2001, WTF?) and I replaced pan, gasket, and filter w/ new from Dealer, as well as refilling with ATF+4. Was hoping this might help problem but it remained unchanged. Today, after using for errands, truck sat for 2-3 hours, when I went to leave, had only 1st gear. Drove home slowly! All other shifts and OD have always been fine until today, never had the RPM fluctuation that others have complained of. Fluid looks good, smells good. Oh, check engine light came on 2-3 months ago. Had scanned @ Autozone soon after. Can't find printout for code # but 99% sure it was "governor voltage reading outside of expected range". (wording may not be 100% correct) Seems like a control issue to me. I hate to just change parts randomly without further diagnostics I'm probably not capable of. Any thoughts? Where should I go from here? Trade it in now on the Tundra I was too cheap to buy 2 years ago LOL! Thanks in advance!
