Well the cel came on today and found it had a fault for
Governor zero pressure malfunction I hooked up the scanner and watched the transmission pressure sensor and it was way off, So I removed the sensors and found the screens where full of gunk. I also removed the solenoids for O/D and Torque converter lock up and cleaned the screens off I have a new sensor and solenoid coming but should I pull the valve body and clean that out? Or are the screens just a common place to collect debris? When I first got the truck I serviced the Trans with new fluid and a filter as the old fluid was well old, so it is possible the new oil picked up the debris that had settled. I have had them open so it would be no problem... just curious.
The truck is a 1998 1500 5.9 the new oil is not burnt but it does have a slightly darker appearance. I also found that when in R there was not pressure but in any forward gear 1, 2, D there was pressure (with the dirty sensor) is this normal or is there a secondary problem?

 

sounds about normal dude... 'specially dealing with a 'not too well maintained tranny'..

you're obviously not skeered to drop pans and pull parts out of that thing.. in the stead of pulling the valve body, if'n i were you, i'd po'bo flush that rascal.. meaning, i'd get some lower end atf+4 and reload it (pssst: WALMART YO).. run it for a couple weeks, and then replace it with some name brand stuff, and put a new filter on it with the name brand stuff..

whilst you're at it.. a remote filter and check delete is a good idea too..

if'n you're really squirrely, a GM mod may be in order.. How many miles is on it?

 

140,000 ish The trans was neglected but shifts great when it’s working. I will be doing the check valve delete, is it possible to drill out the brass and remove the spring and ball? I will be opining up the transmission and installing the sure cure kit, external cooler in the near future with a remote filter, well when the truck and my walled stop dating... Just wanted to know that it sounded normal, and if I should do some mid summer cleaning. So I will run the lower ATF+4 till I upgrade the VB. Tank you for the advice.

 

Leave the VB alone for now. Just replace the sensor. You did the TCC and OD solenoids without removing the VB right?

 

Correct I removed them without removing the VB

 

Me too, a lot of people think you have to remove the VB to do the TTC and OD solenoids.

 

Is there anything other than the bands I should check over before puting the pan back on? There was almost no particles on the magnet.
Thank you both for all your help

 

Adjust them only if you have the correct tools and feel confident you can do it. Screwing that up can get rather expensive.

 

Im not going to touch them I found they are rather touchy on my Dakota. But that was
motivation to beef it up.
