Trouble with auto gear misshifting@ 45/55 mph
 

Hello guys im new on your page ... However any help would be much apreciated
I have a 1994 2500 Ddge automatic 4x4 , and its doing this everytime im reaching 45 to 55 mph, i have already replaced TPS and it worked fine then about 2 min it did it again, any other tips out there anyone.? Thanks in advance

OD solenoid

Thanks for the reply... But if it was the od solenoid would be no od , right?

and no lock-up in 3rd i believe. if it is only kinda working things could be intermitantly slipping/reving high... any other symptoms?

Is it going in & out of lockup

Having the same issues.
TPS sensor and computer? <--BD diesel sells a TPS voltage thing. Have it not installed yet. Believe it sets the right voltage from the sensor to the computer?

Throttle valve cable? adjusted right? <-- Mine is bad and sometimes loses adjustment and depending on my throttle position, jumps in and out of lockup.

Speed sensor? Different tire size and shift points get confused.

Am i close with any of this?
:pca1:

Mine did the same about 4 years ago
With scan tool I could see I was loosing tps
Voltage replaced tps took care of it.started
Doing again last month watched with scan
Tool tps working normal started watching
Other sensors found trans temp sensor reading
As low as 50 deg. In lock up & would jump up
To close to engine temp & it would go in & out
Of lock up while it was showing that
That trans need to see throttle position&
Trans temp above 60 deg to go into lockup
$20.00 trans temp sensor took care of my
Problem

That with a stock trans, or any valvebody work?
Where is the temp sensor for the trans? Its not the one in the cooler line i hope????? If so then maybe that is why i never fixed the problem I have and why its all over the place. i was waiting to put my trans temp probe in the cooler line and redo the lines with a bigger cooler. The wire to the orig probe in the trans line has been ripped off since i got it. Thought it was for the idiot light unless im wrong?

Trans temp sensor is on trans cooler line on
Driver side at the transmission

:argh::argh::argh: Maybe i should get under there is put on a new connector on it and it may actually run right..

Did you go with a mopar sensor, Standard, chepo?
