Engine/Transmission (1994 - 1998) trans problem

[LFowler]

Trans will not shift out of first unless i lift off the accelerator and will shift back if i press the pedle to hard. I have a 1995 2500 12valve auto problem started after i went through a car wash that sprays the undercarage i dried all connecters did not help,:{

you need to provide more info on your truck so we can have a better idea of what it might be #@$%!#@$%!#@$%!#@$%!#@$%!

Those jet sprays could have dislodged something that was loose to begin with. .

Have you ever done the 3-power-on sequence to retrieve codes? (ie. . turn your ignition on 3 times, then leave it on the 3rd, and your CEL light will flash a number of codes, ending in a 55)

post those codes back here and we can help ya more

good luck

It seems to me that your trans is operated by fluid pressure not the PCM. Contact JOE G. he has a 95 auto trans and he would understand the trans better. You can find one of Joe's replys in Help fueling problems, in this forum and e-mail him from that post. https://www.turbodieselregister.com...n-1994-1998/199349-help-fueling-problems.html

There is nothing electrical that can cause these symptoms. If it were not for the problem starting after a pressure wash I would say that the TV (kick down) cable was too tight. There is a spring on the TV lever on the trans. Check to see if the wash knocked it off so the lever is stuck to the rear. Also check to see if the cable to the lever is in the mounting bracket properly.

The code fro the computer was 3 the 55 hope that helps

 

[Joe G.]

The 3 is in the anti-lock brake system in my service manual. It says open dump valve. The 55 is the end of codes indicator. There is NOTHING eletrical involved with the 1, 2, or 3 shifts in a 47RH transmission. It's all mechanical and hydraulic.

thank you

Well droped the pain found some kind of gaskit materal in the bottom looks like a rebuild to me

LFowler, you might want to check the anchor for the front band. It mates up to the adjustment screw for the front band. I've had this same problem happen to my V10 gasser three times. On mine, one edge would break and the anchor would fall out. When this happens, the trans won't shift into second gear. I currently have the transmission tore down in my gasser and going to try and eliminate this problem once and for all.

 

[Joe G.]

The anchor falling out is usually caused by loosening it too much when adjusting the front band. The band material is so thin on these transmissions that they should not be adjusted. If you do it right the result will be exactly where it was before the adjustment. The adjustment really sets the shift. Too tight and you have a bind during the shift. Too loose and you have a slip during the shift. Once you get it right leave it alone. There is not enough material on the band to allow any wear at all. It's only about 1/32" thick.

I have a 94 v10 with a bad motor and good trans will it work

 

[Joe G.]

Kind of. I'm not sure, but I think the torque convertor has a different stall speed. I know the governor is different. The governor fly weight is different. An experiment I know of that tried the V10 governor in a 47RH behind a Cummins had a strange shudder at crusing speed. It was not bad, but it did that. I was considering replacing the governor weight in my transmission with the V10 governor weight in order to raise the shift points for 1-2 and 2-3 shifts I discussed it with a guy in Oregon. He was doing some stuff with diesel hot rods at the time so he tried it out in a test in his shop to see what would happen. The V10 governor weight developed an oscillation at highway speeds in his test. The diesel version of the 47RH has a two piece governor weight. All the other RH versions use a three piece governor weight.
