Throttle Lever Adjustment
|Visit Geno's Garage
for Truck accessories.
The throttle position sensor, shift lever, and throttle valve cable are critical to proper operation of the transmission. If one or more of these are out of adjustment or if the TPS is noisy, shifting will be erratic. Before performing any adjustments, check the transmission fluid level and sniff the fluid. Do not make any adjustments until the fluid level is correct, and burned fluid has been replaced.
Checking the throttle lever cable adjustment:
1. Turn key off
2. Remove the air cleaner on gasoline engines.
3. Verify that both the throttle body lever (or fuel injection pump accelerator linkage) and the transmission throttle lever are at curb idle position.
4. detach the cable from the control lever stud on the throttle body
5. compare the position of the cable end socket and the attachment stud on the throttle body lever. The end of the cable and the stud should be aligned to within 1/32" at the centers. If so, the adjustment is correct, you are done. - reattach the cable
If the cable is not within 1/32" reattach the cable and continue with 7
7. using an assistant to move the accelerator pedal, note the movement.
Adjusting the cable:
8. detach the end of the transmission throttle cable at the throttle body.
9. Verify that the throttle lever on the transmission is in the closed position and the throttle body lever is at the idle position.
10. Press the cable lock release button (on the back part of the cable retainer)
11. with the button depressed, center the cable end on the attachment stud to within 1/32" and release the lock button.
12. Re-attach the cable and verify the adjustment The important part is that the two levers should move together.
When this adjustment is correct, the 2 to 3 shift should occur between 20 and 30 mph under light throttle conditions.
There is a web page with some ideas for modifying the adjustment to alter the shift points. I don't know who did the page, but you can make your own decision about whether or not you are interested. See: http://www.jcj.net/dodgeram/trans_adjustment.htm
This is not approved or recommended by DC, but I thought you might like to see what the had to say and archive it for future reference. If you try this, monitor your fluid for any signs burning which would indicate clutch slippage.
