01 cummins trans problems

[Danberry14]

ok guys any advice and idea new to the forum

I have a 2001 2500 5.9 trans started slipping I found a used one for a good price and purchased it only had 15,000 on rebuild

it was out of a 99 installed and had no o/d or lockup unless I used the l/u switch still no o/d replaced the governor pressure solenoid and sensor without any luck I'm getting ready to replace to o/d solenoid so I have to drop the valve body and ideas of advice is greatly appreciated this is all my first experience with transmissions

are you %100 sure it worked when it was pulled?

[Danberry14]

Yes I am but when we moved it around it worked all that gunk loose and stopped up the sesor I believe

Any codes? If its the governor/solenoid you'll get a code. Also save yourself some headaches and just replace them both. I work at the dealer and whenever someone comes in I practically make them beg me to sell just one at a time because I got sick of customer coming back yelling at me for the sensor not fixing it so from now on I only sell both at the same time.

 

Assuming it is a good trans and all that.... How about your TV cable (throttle valve, kickdown etc.) or the connectors and wiring going to it?

 

Am i reading this right are you saying you have a lockup switch? Hows the jumper wire? Or is the relay still in there maybe? You guys didnt take apart the extension housing at all im assuming because thats the O/D housing as well.

 

Im just throwing suggestions out there and hoping to help

99s and 01s have different electronics in the tranny/valve body. Did you swap the tcc solenoid and pressure transducer from your 01 tranny? Governer solenoid is the same.

No we did not swap the electronics over I’ve replace the governor sensor and solenoid already I have the overdrive solenoid just have to install I’m going to work on it this week and advice when pulling the valve body
