About 2 weeks ago, A couple of times while I was coming to a stop my RPM’s would start to drop fast and the truck would die unless I goosed it a little. So, I did the usual cleaning\checking stuff. I cleaned the IAC and checked the TPS voltage (it’s at .99) etc… and it seemed ok until yesterday.

Here is what happened yesterday:
Coming to a stop from around 55mph after driving about 30minutes the truck died very quickly because it didn't downshift (or that’s what it felt like to me). I immediately put it in park and It started right up, When I went from park and put it into drive the RPM's immediately dropped to about 500 and it was going to die again. That's when I started giving it a bit of gas and doing the staging thing, barely moving forward using the brake. During that process it felt like it downshifted, I felt a little kick or bump, anyway, it corrected itself and all was well. I stopped several times after that and no problems.

Now, after working with usahooters, my tuner, to verify that it wasn’t the chip\tune (it does it without the chip also). It sounds like the converter is staying locked. When it does this it does feel like you are coming to a stop light with a manual tranny and forgetting to push the clutch in.
It did it twice yesterday and so far not once today?

From the searches I have done this isn’t to uncommon. What is, is the fact that I haven’t seen a lot of fixes mentioned other than the IAC,TPS adjust\clean stuff. Hope this isn't a bad thing.
Could one of these parts cause this?

Tuck info:
I have 41k on the truck
Mods in my sig.
I flipped my chip off and it still did it.
New fuel filter, air filter.
I haven’t changed the tranny fluid but it still looks good and red and the levels are good.


Other than this the truck is running great. No odd shifting or anything. I even went out yesterday and ran it hard, something I don’t do very much. I did a few kick downs, used O\D to force some downshifting, turned the air on\off etc.. anything to get it to act up in some other way. It ran perfect and get this, it never tried to die once and I did a LOT of stopping.


If it’s the converter what are my options? How the heck do you even verify if it’s the converter?
In one search I did see where Greg E. mentioned that a solenoid on the converter can cause this?

Thanks for help\tips\suggestions

Well I have had the solenoid and converter replaced and my truck is still dying at stop lights???

Greg E. has been very helpfull but it's impossible to diagnose this via email.

Basically the truck dies about once a week when coming to a stop.
It's like you are forgetting to push in the clutch on a manual tranny.
Twice it has actually shifted or the tq converter locked up while sitting at a red light, the truck tried to go but quickly died.

It did it again today and I new it was coming so I dropped it into first and it still tried to die. I put it into nuetral and then I was able to put it back into drive and keep going but when I took off it wasn't in 1st, more like 3rd or 4th then it was fine again. Now it will probably not do it again for another week.

It's been scanned numerouse times and there are no codes.
THe dealer can't find anything either.

Anyone had this problem before?

ideas??
