CEL cam on my 97 ram 5.9L with 218K on the odo, original engine and trans, never rebuilt.
Seems like truck doesn't have power under acceleration, I can floor it and it won't downshift on the freeway.
I did the ignition switch thing and got code 37 which says trans temp sensor voltage out of range or open short in wiring or connectors. What connectors? trans connectors??
Where do I start? I guess I have to take it in to the shop.
Any advice is appreciated if any of you have had the same code pop up.
I scanned the pcm and got the exact code of P0753 shift solenoid
Thanks!

 

On yours, trans temp sensor is part of the governor pressure sensor. Connector at the trans is the 8 pin, about halfway back, on the drivers side. Goes straight down into its female counterpart. You can check the wiring, and the connector there. Make sure there aren't any bare wires, and the connection is clean, and tight.

 

Awesome man, thank you, I will check that out and see what is going on down there. Hopefully somethng just came loose and thats it.

 

Well, I climbed under my truck, and all the wires and plugs were snug and not exposed. One plug was a little dirty and oily, so I wiped it off, and gave it a twist, and it moved ever so slightly, the one right above the tranny pan on the drivers side, other than that, all appears to be good on the outside, so I am guessing it's the temp sensor inside the trans on the valve body. I got to take her in as that is out of my realm of experience.

 

It's really not that bad of a job. Just grab yourself about six quarts of some variety of ATF +4, and a filter kit. (and, of course, the sensor you need....) Have a large bucket of some sort under the trans, remove all the bolts except two, right at the front. Just loosen those a turn or two. Then, get the pan to break loose. LOTS of fluid will come rushing out. Be prepared. (the wider your bucket, the better....) Let it drain down, and then loosen the two screws a little more. (more fluid will come out.) When they are just about ready to fall out, support the pan, remove them, and then dump the rest of the fluid into your bucket.

Pull the filter, swap the sensor, put new filter on, clean out pan, use the new gasket, and put it back on. Don't overtorque the bolts, that causes leaks. Add four of your quarts of fluid, and start the engine, run it thru all the gears, (don't have to move the truck, just keep your foot on the brake.) Leave the truck idling in neutral, set the ebrake. (if it works... if not, block the tires so it won't roll.) Check fluid. (MUST be in neutral to be accurate) It will probably still be low. Top it off, take it for a short drive, check it again. Clear the codes. (disconnect battery, turn on headlights, count to five, turn off headlights, hook battery back up.)

See if the code comes back.... (it shouldn't.)

 

Thank-you! You make it sound pretty easy I should be able to handle it! Do you know if the tranny pan bolts have a specific tourque setting?

 

Yes, as a matter of fact they do. And a specific pattern to follow while torquing as well. All of which can be found in the factory service manual. You can download one in PDF format from the Service manual thread in the FAQ section here. Get the 96 version, it should be exactly like your truck.

 

I actually did that before, so I will refer to that, thanks so much for all your advice

 

While your at pick up a oil drain plug kit
I believe you drill a 1/2" hole to install it.
Makes way less mess next time.

 

Thats a great idea, thanks for the tip
