no overdrive with DTT TC and VB

[tobaccogrower]

just had the 91% DTT TC and VB installed this wweekend. now, the truck wont shift into overdrive unless i take my foot out of the throttle!i have a 4:10 rear. i was merging on the highway yesterday and the truck revved to 3600rpm and wwould'nt shift untill i let off. i can't wait untill i get this fixed! the truck pulls like a bear through third, and when it shifts into 4'th,i have to keep reminding myself i'm driving a ttruck,not a FERRARI!!!i was thinking of DD11's but that might be too much for me..... NOT... . thanks... james... .

You might check the adjustment of your throttle valve cable. What are your WOT shift points on 1-2,2-3? Did you check the voltage at pin 31 on the center conn. at the pcm for around 4. 6volts? You may have to install a resistor in that wire to reduce the voltage. Throttle position sensor is involved also on 3-4 shift. Hope this helps.

CALL BILL K!!! If I recall correctly. . there is a cable down by the transmission... in which if it is not hooked up you won't get into OD. But you need to call Bill immediately!!

The 3-4 shift is computer controlled. Go do that scenario 4-6 times and the computer will relearn where to shift.

H. O. , interesting post , i would have expected you to tell him to call the other shop in abbotsford #ad


and a question about your sig ? are you REALLY glad you didn't buy the auto ??? #ad
... edit , H. O. having seen your truck and the problem created by larger than stock tires i now know why you are glad you didn't buy an auto . #ad

Edited, as I didn't fully understand the trucks scenario:

RamHead3437, I'd call Bill K. to get his take. Sounds like something didn't get connected properly. Did you do it yourself or have a shop do it? If a shop, take it back, they missed something, its called a road test. That's part of Bill's complete package, verify everything before and after. Pressures, light throttle shift points ,WOT shift points and kick down cable alignment.
I understand all of the above was performed, and is right on, as posted above by MM. Sorry MM, it was late, and I didn't completely read your post(it didn't register).

Sounds like a reflash is in order. Sometimes there is no other route but the dealership to get the necessary work done. The PCM contols OD, therefore a reflash should fix it.

EDIT ... . i have to rephrase this as i came across a wrong in my response .

resistor is in , voltage is correct , shift points are correct .

here is the paragraph on the how the computer controls the shift and relearns taken from the 2000 shop manual section 22 page 189 ...

Wide-Open Throttle Operation

In wide-open throttle mode (WOT) adaptive memory in the PCM assures that up-shifts occur at the preprogrammed optimum speed . WOT operation is determined from the throttle position sensor, which is also part of the emission control system . The inital setting for the WOT upshift is below the optimum engine speed . As WOT shifts are repeated , the PCM learns the time required to complete the shifts by comparing the engine speed when the shift occurs to the optimum speed . After each shift ,the PCM adjusts the shift point until the optimum speed is reached . The PCM also considers vehicle loading , grade and engine performance changes due to high alitude in determining when to make WOT shifts . It does this by measuring vehicle and engine acceleration and then factoring in the shift time .

the vehicle in question is confusing the PCM somewhat due to speedo error created by non factory installed tires and the speed signal not being corrected . this is not a problem with a manual transmission as much as the problems it creates when done on an auto equipped ram .

Bob,
Can you tell me where in the guidelines it tells about your sig?

Actually I am perusing the auto threads because my Step-Mom has a '99 auto and ever since I let her drive my truck she has been begging my dad to make her's as fast. #ad

Mopar Muscle, Yes I am glad. I wanted the
6-speed with 4. 10 gears so when I put my
315/75R16 tires (last week) my final gear ratio is 3. 74. I can drive my wifes car if I want to drive an auto. Its not that I dont like them it is my preference to shift gears #ad
