I just need to know if this is normal, or cause for concern? Once my operating temps are up to snuff sometimes when I'm coming through the gears when my truck should drop into lockout for the overdrive it won't drop in. I can gradually apply gas and the rpms will just rise. If I nail the gas good and hard to get it to drop back down to passing gear, then let it go back to OD again it usually will go into lock out and I can accelerate without an rpm raise.....

Could this be a sign of my TC going bad?

I'm also getting a slight humming noise in OD at about 1800rpm in OD at about 60mph now that I don't believe I was getting before....? I thought it might be a rear tire out of balance, but I rotated them and it still sounds more towards the rear-end. Am I paranoid, or should I be looking for something?

 

Nobody? Did I not really explain good enough, or is it just something I shouldn't even be concerned with?[&:]

 

there are 2 sensors (govenor pressure & another one which I forget what it's called), they are know trouble spots on the rams. Take it to a shop and have them changed... should cost about $300 bux with a service. Also your torque converter lockup solenoid could be going bad. But 1st i'd do the 2 sensors. I had a problem similar to yours last summer, swapped both sensors and it fixed it...

 

So, this wouldn't be a tps issue?

So, basically I need to take it in to the shop, explain the symptoms, and let them try the sensors? Thanks for the help. Its greatly appreciated.

 

yup, that's what my tranny guy told me (about the sensors) he swapped them both out and it's been trouble free since then.

 

10-4. I'll have to have it checked out.

Steve has some good ideas to check - so I'd do that first. I'll chime in with a couple more ideas. Check your fluid - if it is not pink in color and looks and smells burnt - you possibly have a burnt up tranny. The shop you take it to should be able to diagnose this, if the fluid is bad. You might get lucky and get by with a fluid/filter change, probably not. My first one let go 4 days after a fluid/filter swap done by the stealership. You have the exact same symptoms I had before both of my trannies let go. My truck had a factory 7-100k powertrain warranty since I bought it in Nov 2001. The dealer has rebuilt tranny both times, both times the converter and the overdrive unit was bad. I read somewhere that the od unit in these things has a 845 pound spring in them or something like that - that has to be overcome by fluid pressure. That creates heat and wear on the clutches in the od unit. If the converter goes bad, the added slippage created makes the od work harder. Also makes bad little pieces of metal go through the tranny that it doesn't like.........

 

Fluid looks/smells fine. I checked it just last night. As I said though, I have noticed a hum at about 1700-1800rpm that I don't recall being there before.

 

Found some very interesting info over at "another dodge site". Here is a post from "Stickbow". And again this is courtesy of "another dodge site". Funny that they won't let you post this sites name here...

"The governor pressure transducer modifies line pressure to create governor. The governor pressure solenoid does what the PCM tells it to do. Dodge has had issues with these two guys. Governor pressure should equal MPH until the trans reaches overdrive then the PCM shuts down the solenoid to create max gov. pressure (close to line pressure) sending the trans into 3rd gear and then adding overdrive by engaging the overdrive clutch and disengaging the direct clutch. The limp gear in "RE" trannys is 3rd gear............"

 

Now, I guess the next question for me is....... Has anyone replaced these two sensors/parts before, and what is involved. I'd rather just pay for the parts and do it myself.
