Default Transmission Slip

I have a 2006 Dodge 2500 4X4 Quad Cab with Cummins and automatic transmission. The truck had 10,000 miles on it now and for as long as I can remember when the truck is cold and you put it into drive you really have to rev up the engine to get it to move. After about 5 seconds of warming up no more slip. I spoke to the dealer and they said it was normal. Any thoughts? Also, I usually put it into drive now and wait a couple of seconds before taking off. No slip that way. I checked the fluid level and it is full. Thanks for any help.

It is normal for it to do this after sitting for a day or so as the fluid drains back out of the torque converter and the trans pump does not pump fluid back into it in Park. This is why you should never idle in Park for more then 10 minutes as it can burn up your trans as a Dodge Torque Flight type trans has never pumped fluid in Park.

If I leave mine setting for a day or two it can take 20 seconds or so before it will move if I drop it in gear just after starting it up and its cold outside. All I do is put it in N and wait for 20 second or so put it in gear and it moves just fine. FYI, you can Read about this on page 263 in your 2006 Dodge owners manual.

Jakebrake,
I just wanted every one to know I was not BSing them nor was I making it up about the trans not moving if it has sat for a day or more because many don’t know that the fluid will drain out of the torque converter. Also a lot of people still don't know that a stock Dodge trans will not pump fluid in Park. I felt if they can look it up in the manual then they can verify what I posted was true.

The big N is OK as that is gear where I warm mine up. The pump in the trans will work in all gears including Nuetral but not in Park. IIRC all it has to say in owners manual is to not idle for more then I think 10 minutes in Park becasue of the turbo and they forget to tell you that you could hurt your tourque converter if left idling to long in Park.

Mine was sort of doing this but it turned out to be a bit of Turbo lag. I would hit the gas and the truck would not really get moving until the RPMs passed about 1300. Most likely though it sounds like your problem is the TC with no fluid (as described by others).

If your talking about the fluid not pumping fluid in Park then yes it applies to all Dodge's with a torqueflight type trans.

mine has never done that... there is a check valve in the lines that is supposed to keep the fluid up in the converter & cooler to prevent the drainback into the pan. Go test drive another new one and see how it acts... I can almost guarantee you it wont act the same as your truck. your dealer is trying to dodge the problem.

IIRC Dodge started to make the torque flight trans back in the 1970’s maybe earlier anyway the trans in our truck is a cousin too the torque flight, in fact some of the parts in our 48RE will still interchange with the older trans. IIRC our stock Dodge trans does not and never has pumped fluid in Park, but you can modify the valve body to make it pump in Park.


In my 2006 owner’s manual on page 263 it has a few words about how the tranny will seem sluggish the first few second of operation after going in to gear due to some of the fluid draining out of the converter, its normal and will not hurt the tranny. Also the converter will fill with in 5 second of shifting out of Park in to any gear. IIRC a rebuilder over on the Diesel Ram Forum showed a photo of what happened to one person who left his truck idling in Park for I think it was 8 hours maybe less, maybe more anyway the damaged and broken parts sure did not look pretty and I bet the rebuild bill wasn’t either.


Like I said in on of my post above, mine will do it but I notice it more when it’s cold out side or if it has sat for several days. IMHO this is one more reason I want to switch my trans to Amsoil ATF fluid as it flows much better and holds up better then Mopar ATF does. I just remembered that I read of a person who said his TC would drain the fluid out of it in like 5 hours. It is also possible you have a trans that is not right and needs to be looked at, so if your dealers will not do any thing then I hope you have another one close by you can go to and see what they have to say.

Oh it must be nice to want it to break so you can go spend $5,000.00 to get an AST Tranny.

DBLR, is there any reason to believe that a normal transmission service and fluid change would fix slippage problem at a cold start? Also, would this be a precurser to transmission failure at 200K miles on a 2005 diesel? Thanks! Rich
