47RE acting odd....
Alright, a little background, my trans is 14 months old, it has 15,000 miles on it since the rebuild. When rebuilt, it got a precision industries billet torque converter, transgo shift kit, all new electronics, all new clutches, steels, & bands, and a double deep pan.
The trans has been awesome since the rebuild, working perfect, and trans temps in the 140-175 range the whole time.
Heres the issue, today it started acting like the converter is not unlocking. When I stop at a light, the truck tries to push thru the brakes and keep moving. If I put the truck in neutral, everything is fine, but when I drop it in gear again, the truck almost stalls, then takes off on its own. All the gears are working fine, and the trans fluid is bright red. It just seems as if the convertor is stuck locked up.
Whats the deal?
Thanks in advance!

Do not be alarmed if this does not fix the problem. The solenoids have about a 2 in 10 drop rate for failure. I'm just saying you might have to do it twice.

Well, I dropped the valve body today, and replaced the lockup/overdrive solenoids. And the truck is still doing the same thing. I tested the old solenoid on the bench, and it works fine.
Any other ideas?

Thanks again for the info guys,
I'll drop the pan and valvebody again tonight, and see if thats the issue. Shame on me for not pulling it apart yesterday when it was on the bench....
Well, I'll update this again when I check the spiring and barrel.
I should just have velcro holding the trans pan on, and wing nuts on the valvebody at this point!

Well, I pulled the pan & valvebody again, tore the valvebody apart, & everything is in good shape. All of the valves and barrels look great, and the springs are fine too. I replaced the valvebody again, but left the wiring disconnected from the trans. I started the truck up and it still does the same thing....

I talked to a buddy today that works in the trans-lab at chrysler. As soon as I told him the symptoms, he said "plugged trans cooler". Im still not sure how that would affect lockup, but he told me to loop the cooler lines tomorrow, and bypass the coolers and try it out.

I just started having the same problem. In the last 20,000 miles I have had 2 transmisions, rewired the apps sensor, adjust the voltage to the apps sensor. Suddenly the truck was shifting better then ever.Then all the sudden this shifting problem from park to drive or reverse, if i slam it into gear a few times, get the truck to a slow roll and start it from neatrul i can get it going, but stopping is ---king dangerous. The truck is at 1200 RPM's and when I lift my foot off of the break the truck accelerates to 25 mph before it stops acclerating, the tran only has 2300 miles on it. The dealership currently has it but the problem is intermitent and they do not see a problem.
