SOURCE: 1998dodge1500 wont shift from 2nd to 3rd unless I let off the gas

Well, I should be asking for more information, but since I am now on my 5th, yeah, 5th transmission in my 95 1500 Ram I have come to learn a little bit about them. Chrysler had a bad problem with their trannies in the 94's & 95's. They then made a change in 96, but that didn't solve the problem. So here goes my attempt to help you out.
Have you checked you tranny fluid level? Very important. A transmission kind of works under the same principal as a jet boat. Meaning, it pumps the fluid through the transmission much the same way a jet boat pumps water through it to move the boat, but in this case the fluid power is directed through several lines causing the gears to move. You switch gears when there is a certian amount of pressure on the modulator to divert the fluid to another area.
Long story short: Check your fluid, not only the level BUT the fluid. Are you seeing any metal in it? Dodge had a problem with the webbing of their torque converters flaking off, causing transmission cooliant lines to plug up. This same metal chips, shavings, etc. were damaging the face of the clutches, and plugging up modulators. Check your fluid. I would probably say change your fluid and transmission filter. It's not that big of a job if you have a place you can work on your vehicle. Be careful when putting you transmission pan back on. Make sure you tighten the bolts in a crosswise manner, and tighten them snug, BUT not over tight. That will cause leaks.
Another point I will make. Check for vacuum leaks, this could very well be your culprit too.
I'd start with that first.
Good luck, let us know how you come out.

Hello,

The shifter problem is likely related to worn nylon bushings on the shifter or a broken shifter quadrant (the PRNDL). You will need to disassemble the center console in order to pin down the problem. Procedure is found in the shop manual.

The shifter problem and the gear shift hesitation are likely NOT related. Usually, a delay in shifting is due to being low on automatic transmission fluid. Check your fluid with the engine running, and warm, car in PARK (be sure the parking brake is on for safety's sake.)

The transmission fluid dip stick has a red pull top and is at the rear of the engine. With a clean rag or paper towel, clean any fluid or dirt from the bottom of the stick and reinsert it into the tube. Pull the dip stick out the second time and note the fluid level. If it's between the top and bottom marks, it's OK UNLESS:

1) There is no fluid indicated: Add sufficient Dexron III or Dextron IV to bring the fluid to the correct level. (Remember that the dfistance betweeen the marks is in PINTS, not quarts like the oil.) Do not overfill the transmission.

2) Fluid should be ruby red in color and have a neutral "oily" smell. If the fluid has a slight yellowish color or smells "burned", you may have internal damage in the transmission. Best thing to do in this case is to have the transmission fluid and filter changed and proceed from there on your trouble shooting.

Best of luck,

Dr of Motors

There are several possible causes for this symptom. Your regulator is integrated to the fuel pump inside the fuel tank. Unless the problem is in the wiring, the pump will probably need replacing. A mechanic can check the wiring for you or you can check yourself with an ohmmeter.

Rpm are very high and wont shift in to gear unless i let go of the gas pedal


Before guessing at transmission problems, check the fluid level (car warmed up, engine running in Park on level ground) and have the PCM scanned for trouble codes FIRST. This guide is meant for problems that do not show up as PCM codes (like shift A&B solenoid failures, for example)
1-2 shift does not happen at WOT until you let off the gas: Best case: try replacing the TPS. Middle case: leak in the 2nd gear apply circuit (servo assembly or 1-2 accumulator). Doublecheck by using the pressure gauge and watch for a big drop when the PCM commands 2nd gear. Worst case: poor line pressure rise (see below)
1-2 shift is delayed and harsh, may not shift into OD: Check TPS for smooth and linear electrical response over the entire range of motion. If not, replace.

Wont shift past 2nd


Find your throttle valve cable attached up near cable from throttle pedal ,it's the one that runs down behind toward transmission. With engine off in park,park brake on, Have someone push gas pedal to the floor & observe that cable, to make sure it is retracting properly when pedal released. Now get under & watch where that cable attaches & watch it while doing the same with gas pedal. The lever that it attaches to should move freely & rotate one way when gas pedal pushed, and should return all the way the other way when pedal released. Sometimes that linkage or cable will get seized, and not return fully, which will hold transmission in lower gear. You can use your hand to make sure it is returning all the way if necessary, and if needed, apply penetrating spray to loosen it up, then apply something like white lithium grease to coat it after it's unseized, to prevent repeat in near future.

Transmission wont shift out of park


Try checking the brake light sending unit. Are your brake lights even working. Many newer vehincles will not shift out of park unless the brake pedal is depressed. However, a faulty sendind unit located on the pedal itself can keep you from moving anywhere. Just check to see if your brake lights are working to know if the sending unit is working.

Suburban wont go into gear


check to see if your brake lights are working.there is a safety system that wont allow you to shift from park unless you push the brake pedal........most of these systems utilize the brake light switch for this........if your brake lights dont work it is most likely a blown fuse.
hope this helps....
