Take a look at the down shift cable and make sure its not broken especially were it connects to the throttle linkage.And maybe try cleaning the electrical plug that plugs into the trans.Its about a 7 to 9 wire plug.They tend to collect water and short the wiring out.

2004 Dodge 3500 4x4 , torque converter lock up problems

The bad ground answer seems to be the most plausible answer. I had the same problem with my diesel 48RE transmission.

I remembered a condition with the Intrepid where the instrument cluster lights and dome light would go nuts. The solution was to pull the plug from the back of the cluster dimmer control and apply electrolytic grease.

I applied some to my Transmission Range Sensor connector and haven't had any trouble since.

1. Diesels don't use vacuum
2. Fluid level won't affect TC lockup
3. Replaced the TC lockup solenoid array which did not alleviate the condition.

UPDATE: The electrolytic paste in the plug did help for a time. However, eventually the torque converter failed about a year later and filled the transmission with metal filings :( I replaced it with a high-performance TC.

I have a 1999 Ford Explorer Sport. It sometimes stalls when coming to a stop. Ussually after driving several miles. It will restart in park and idle fine. But as soon as I shift it into drive it will die....

Go to a local transmission shop, an independant if possible, and ask them to test drive your vehicle.This is a more common problem with GM vehicles, but it sounds as though your trans may not be coming out of lockup, causing a situation very similar to pulling up to a stop with a manual trans , and not depressing the clutch. Lockup is designed to kick in at cruise speeds, and remove all slippage from an auto trans, thereby improving milage. Sometimes the trans will not unlock. The good news is that many times, it's not a incredibly expensive repair. Good luck!

Transmission- 2001 Dodge ram 2500 diesel 4X4

I have a 2002 Dodge Ram that doesn't like to shift into 2nd when flooring it from a Stop. Imagine if you were to floor the gas in neutral, the engine REDLINEs and the engine governor kicks in to keep the RPM from blowing the engine......while stuck in first Gear. If i let off the gas, it goes into 2nd fine. I have replaced the Speed Sensor on the transmission ($18) and it seemed to fix it for one day. After 200 miles, its doing it again. ANybody have legitimate answers in here? Its only got 60K
