My '02 3500 Ram turned 50K recently and I thought it would be a good idea to change fluid and install a shift kit. I've let it be known I didn't care for how this thing shifted from day 1 and had it to the dealer a couple times. It seems to want to hunt for gears when towing or when in cruise would downshift for a grade then never upshift on it's own when on a flat.( I let it go for miles just to see when) Anyway most of this stuff was cured when I turn the OD off. Enough history for now.

I installed this Trans-Go kit and followed the directions as best I could and now have a problem with 1-2 shift. From a cold start seems ok but as the trans warms it acts up. What I thought was slipping is it wanting to start in 2nd gear. Stopping then going to reverse then back to drive seems to correct it but will flutter between 1 & 2 depending on throttle position. Idleing thru a parking lot I can hear it shifting in and out of 1st but don't really feel it. Occasionally from a dead stop it will shift normal. 3rd, OD, and convertor lock-up seem normal.

By the time I had disassembled the VB on my bench I wished I had paid someone to do it but it was too late. I'm only assuming it has something to do with the 1-2 accumulator but don't know the full mechanics of any of it. Typing this all out is easier than trying to explain this over the phone to someone. I am embarrassed this didn't work out and could really use a little guidance.

Mine did the hunting and start in 2nd thing and I changed the solenoid and sensor in the valve body.Fixed it.

I can't give you any help, just advice. Start over with the instructions and make sure you didn't miss anything. If you are good there, take the FSM and see if there is some other problem that the shift kit didn't address. Sorry, best I can do.

When you say "followed the directions as best I could" what part didn't you do. Also you mentioned you never liked the way it acted before the repairs so the kit may not be the problem it just may be more noticeable now. Lastly what did the oil look like when you drained it the first time.

What in the kit makes it a pro installed kit only?

ASSuming everything in the shift kit was installed correctly, you really need to hook a scan tool to it and monitor the target governor pressure vs actual governor pressure. With the key on/engine off monitor he actual governor pressure it should be reading zero. If it is reading some sort of pressure the governor pressure sensor/transducer is bad. If not, start and drive the truck. Monitor the governor pressure while taking off from a stop it should read closely to the speed you are going, i.e. 10 psi = 10 mph. It should do this until it goes into overdrive and lockup and then the pressure will spike to well over 100 psi. Pay special attention to the gov. pressure when coming to a stop. It should drop to zero. If it does not there is an issue with the governor pressure solenoid. If I were to guess, I would say you need a governor pressure solenoid. It is very common RE transmissions. Do you self a favor and buy a MOPAR one. I personnaly have had bad luck with the aftermarket units.

Have you had the transmission fluid flushed? Could be the solenoid or a small part in the trans???? I am not a transmission expert, I just play as one on the web:)lol Seriously it could be serious and require a rebuild Hope it isn't

I,m not an expert and have only built a few transmissions but I do have the ASTG manual that covers the 47RH and a diagnostic manual for a 46RH which states. "Shifts delayed or erratic"

Low fluid,
Throttle linkage adjustment or binding,
Gearshift linkage,
Plugged filter,
Air in fluid due to overfill or air leakage into pump suction passages,
Clutch or servo problem,
Front band out of adjustment(may cause harsh 1-2 shift)

Does yours have the plastic accumulator they can causing problems.

This may help you get some thing eliminated.

Your original problem was more likely one or both of the vb switches.. solenoid or sensor
The tranny will act up exactly as you described

As far as the TransGo kit problem.. Double check your work and put it back together with a NEW solenoid and sensor. Heavy Duty vb electronics are sold on Ebay too but not sure if HDs are needed.

just my opinion

did you put the heavy duty front band piece in maybe front band out adjustment,also did you turn pressure screw counter clockwise,i think 1 turn

Took a severe beating with a 2wd ram 1500 version of this unit years ago.Used that super duper canadian major VB modification deal.
had the pan off like 5 times, the thing that I missed that got it all happy again was the
(hope I say this right)pressure regulator and pressure sensor located on the side of the VB.If the trans gets the slightest bit of dirt in either of these (ie fluid a little burnt)it will NEVER work right.in desperation I contacted a well known trans rebuilder in AZ or Nevada I think and bought those 2 parts for like $75.
easy install and the truck is still driving, albeit not perfect, but usable.
