The relay has pin ID on it lets use that. CAV 30 is B+ which is 12 volts, Cavity 85 is transmission control relay. Cavity 86 is Generator source. Cavity 87 is transmission control relay output. Cavity 87A is not used. open that relay and exposed the relay control see if it engages on its own if not collapse it see if you get out of limp mode.

If you are looking for the fuse box diagrams or any other diagrams for your Ram, check promanuals.net for a factory service manual for around 20 bucks or so. It's an invaluable tool for my Ram 2500.

SOURCE: 2002 dodge ram 2500 diesel

I'm no expert, but I am on my second Dodge. I have a 2004 Ram 2500, 125k miles on it. I traded in my 2001 1500 with 99k on it.
Your problem sounds like one of two things that happened to me. At 110k mi's it was not accelerating properly, particularly between 40 and 50 mph. It turned out my torque converter was going bad and I ignored it for too long and it's disintegrated pieces ruined my transmission. I recommend getting over to Aamco right away or to the dealer if you are still in warranty and have the TC checked out. The diesel is just too much torque for a torque converter on the automatic transmission, but manuals are too much of a pain these days. $2300 at Aamco to have the TC replaced and the tranny rebuilt.

The new problem I have now is when it acted like it was out of fuel and then wouldn't turn over after it died. My fuel lift pump (diesels have two of everything and the expensive one is always what goes) has gone bad and is currently being replaced, $700 part, plus another few hundred in labor.
Hope this helps.

SOURCE: 2006 dodge ram 2500 a/c fuse rely

The AC relay is located in the under hood fuse box. The cover should have a legend for location. Its one of the bigger black ones. You can rotate it with the horn or ABS one to see if its the problem. You may have a small fuse also in that box for it. If this doesn't solve the problem then you either have a leak or a computer problem. What a shop will do is try with a bidirectional data scanner turn the AC on. If they can't get it to turn on with a scanner then you most likely have a failed PCM if they verified you do not have low pressure or a relay or wiring or switch issue.

SOURCE: 1996 dodge ram 2500 auto transmission not shifting properly

Well, first do the service. Pull the pan down and look for metal shavings. If there is metal shavings your in for a transmission. If not, you may have a problem with one of the transmissions shift solenoids located near the valve body.
P.S. The Duramax has the Allison 1000 transmission not the dodge cummins and they are one of the best trannys on the market.

4 cyl. Auto trans. in limp mode. takin the shift solenoid out to re build it i fnd ripped wires. My question may seem should i re connect the first or cont with the shift solenoi


Unfortunately, you should have gotten the diagnostic codes for the transmission before messing with the shift solenoid. Most of those dodge shift issues are caused by input and output speed sensors.

I have a 2004 dodge ram 2500 stuck in limp mode. Can't get it out of limp mode any way to dypass?


Not really. You have to have the codes read. Could be as easy as replacing a solenoid. You have to remove the transmission pan to do it. Or it could be a transmission rebuild.

Why won't my 97 dodge caravan auto transmisson shift as speed increases, transmission fluid level is good?


Could be running in 'limp mode'. This is due to a faulty sensor in the transmission or wiring problem. It is a way the computer protects your transmission from damage due to a bad signal from the transmission sensors . Other recommendations from the Dodge forum are:
"stuck in limp mode there are a few things you can do to fix the car with out putting a new tranny if you really dont need one. First thing to do would be to change in/output sensors on tranny. $16 ea. Also check the tranny solenoid pack on tranny and check contact points clean out all oil if any in there. Clean really well. This is the problem I had. When oil gets inside of tranny solenoid pack it may ground out causing the service engine soon light to come on. I noticed on mine there was burnt oil and one contact point on the female plug was kind of burnt and black colored. What I did was clean with a needle so the male pin can make a clean contact. I also opened the bad pin with a needle to make it fatter so it will make a nice contact. I put all together and everything worked!! Dodge designed the part incorrectly causing many problems with these vans." Hope this helps.

Trans stuck in limp mode i'm getting a p1751 code


P 1751 Shift Solenoid" A" performance. The solenoid is part of the transmission valve body and yes if this solenoid fails you will get limp mode.The only solution is a new solenoid may be even the wires to it or even the transmission module

2005 Dodge RAM 1500 Quad Cab; 5.7 Hemi: Trouble codes: P1521 Transmission Engaged at High Throttle Angle P0700 Transmission Control System Malfunction P0750 Shift Solenoid A Malfunction Truck feels...


P1521 - VRIS Solenoid 1 I have replaced the VRIS (Variable resonance idle solenoid 1).
P0750 - Shift Solenoid A malfunction
There is more than one solenoid in the valve body and to make sure he is replacing the right one. I will say that with an electrical malfunction code---it's usually the wiring or the solenoid----so not a real bad choice. Come to think of it I think there will be 4 solenoids---A,B,EPC and TCC. So he needs to find out which one is the bad one before he goes replacing.

Good luck

Transmission won't shift out of first


You likely have a bad transmission solenoid, which chrysler is famous for. the symptom is just as you describe, car/van/truck shifts down to and stays in first - to get you home in limp mode. Once it cools off a while it may run fine for an hour/day/week and the the problem returns.

Not a real expensive fix.

My 2000 dodge caravan just went into its limp mode for the transmission. It is staying in second gear and will not shift higher. What could be the reason?


The transmissions available in your caravan are problematic for having a bad solenoid pack. Once the transmission is set in the LIMP IN mode, then you need to take it to a dealer to get the code reset from the transmission and to get it diagnosed properly. I'm sure there will be a code such as, "trans solenoid stuck in LR" which means " low range" if the transmission went into limp in mode, then that simply means it defaulted to second gear only. Which is telling you to have it looked at asap. I'm sure if you repalce the transmission solenoid pack and gasket and perform the re-learn procedure, then your problem will go away. good luck!

Transmission- 2001 Dodge ram 2500 diesel 4X4


I have a 2002 Dodge Ram that doesn't like to shift into 2nd when flooring it from a Stop. Imagine if you were to floor the gas in neutral, the engine REDLINEs and the engine governor kicks in to keep the RPM from blowing the engine......while stuck in first Gear. If i let off the gas, it goes into 2nd fine. I have replaced the Speed Sensor on the transmission ($18) and it seemed to fix it for one day. After 200 miles, its doing it again. ANybody have legitimate answers in here? Its only got 60K miles..wtf?
