Question for Auto Mechanics

[Snapshot]

My 1999 Dodge Ram 2500 4x4,5.9l V8 with auto trans has a problem.

 

Diagnostic reader says .....

 

DTC P0500 ...Speed sensor problem.

 

I replaced the tranny and rear diff sensors.

 

I checked the fuses

 

Problem remains.

 

The vehicle starts hard as if there is a load on the engine. will not stay running if I take my foot off the gas, unless it is thoroughly warmed up and driven for 10 minutes.

 

I am a "do it myself" type of guy, and I am a pretty fair mechanic, except for these type of electrical or troubleshooting issues.

 

I have researched the internet, and some guys have had related issues caused by the Anti lock brake module problems? Fuses? Reluctor ring gear?

 

If it was a bad reluctor, why would my truck run fine after its warmed up?

 

Any advice would be appreciated!

I replaced the tranny speed sensor about 9 years ago when it went out. But it didnt have this type of problem.

I have owned 4 Dodge Rams, going back to 1996. Never had any major issues. But my old clunker needs to be replaced with a new one. This truck belonged to my Dad, I bought it from my sister after he passed on. I had an '05 at the time. It has 230,000 hard miles on it.

.....and....there is a considerable amount of transmission fluid leaking out of the bell housing area.

It souds like a torque converter. If you are in drive stopped does it try to lunge forward and really hard to stop.

My son, says speed sensor. He also said it would have to be looked at to be sure.

Get it to a good shop. Doesn't sound good though.

No. It doesnt do that. Awhile back I had a DTC code that came up as torque converter shift solenoid. But it went away?

 

The Transmission has been acting strange for a little while. Shift points seem off a bit, and it hits a little hard.

Funds are tight right now. I just had to pay for some medical bills. I will have to do what I can on my own for now. Its been awhile since I serviced the Trans. This weekend I am going to pull the pan, and flush the trans, and new fluid and filter.

 

Plus it will be a little cooler on Saturday, which means less sweat rolling in the eyeballs. LOL.

An internet article recommended to trace the sensor wires all the way to the main harness, for shorts or bare wire.?

 

If it does lead to torque converter issues, I may end up pulling the trans and install a new TC. I dread having to do that.

I dont think the hard starting or the leak for that matter would be coming from the sensor. If it doesnt stall or buck than its most likely not a converter

When I first start it up in the morning, the engine struggles to turn over, as if a brake was being applied, and it will stall if I take my foot off the gas. It runs fine after it warms up for awhile.? Bur there are no lurching problems that I have noticed.

 

I'm not certain, but the leak may be a front shaft seal, or a leaking TC? I will see if that stamped steel inspection plate will come off and I can look up in there with a flashlight maybe?

Spend the money for an hour of diag at a shop and not on flushing the trans.
