I acquired this 99 ram sport 5.9l 4x4 about a year back with 85k on it and have since put quite a bit of money in it

Recently it started acting up again and it might be because its been much colder out

Basically when accelerating to highway speeds (30-70mph) it will rev up to 3-4k rpm and i will need to let off the gas and it will shift hard

I just replaced the tps hoping it would do the trick but it is still happening any insight on what needs to be done ?>

 

Make sure fluid level is correct, and fluid is in good condition.

Make sure TV cable is adjusted properly.

Verify all electrical connections on the trans, and check the three connectors on the PCM as well.

fixed your plenum yet?

Welcome to DF!

 

yes prior to fixing my plenum my oil gauge would fluctuate and my check gauges light would come on now that is all good. I've put a lot of time and money in this truck to get it running good mechanically and now this! what is the tv cable?

 

Throttle Valve Cable. It modulates the shifts depending on how hard you are stepping on the go-pedal.

Possible that the governor pressure stuff is just having some issues. Wouldn't be the first time.

 

Governor pressure stuff?
Also if anyone else has any ideas let me know i'll be looking into all of this to get the issue fixed

 

On the older transmissions, the governor (controls shifting) was purely mechanical, and worked great..... starting in 96, they went with electronic controls, so the 'governor' is actually a solenoid, controlled by the PCM, and it uses a sensor to determine pressure.

Unfortunately, Dodge, in their infinite wisdom, decided that a self-cleaning solenoid wasn't necessary.... so, it gets dirty, and no longer works right, and you get really strange transmission behavior. You *might* be able to pull it and clean it, but, if you are going to be in there anyway, better plan is just to replace 'em with better parts. Borg-Warner makes a heavy duty solenoid/sensor set, for about a hundred bucks. Get a filter kit, some fluid, and change it all out. Usually, that will fix a host of ills. Also gives you the chance to adjust the bands, and see if there is anything rude in the pan.

 

ah yes i did not know what you meant by governor but my truck is a 99 and i was researching the solenoid replacement never done anything with the transmission but i did the plenum fix myself so i'm sure that wont be hard


Also found this great guide on the TV cable i will be doing this any suggestions on which way i should go with it? It is shifting fine going to 2nd i feel like the issue is 2nd to 3rd or 3rd to 4th when accelerating i'll need to let off the gas for it to shift http://bionicdodge.com/Download/Dodg...Adjustment.pdf

 

That may just be a band adjustment...... or the electronics. Doubt that adjusting TV will have any effect there......

 

If you change the tps how long does it take to notice changes? Instantly or would it take a bit for it to learn? I was just taking it to get a mud bath and it seemed to be running very nicely no issues shifting even putting the pedal to the floor not sure if its becuase its not as cold out lately or the tps was changed

 

Generally, when you change sensors like that, you should reset the PCM, and it will relearn the new sensor in fairly short order. Otherwise, (especially with the TPS) it doesn't see values that it expects, and can lead to some rather interesting behavior.
