What's up with the shift delay in my megacab. The first time I took it in the dealer said there's nothing wrong with it and couldn't reproduce it. I took it to another dealer who said they checked the fluid (DUH) and it was all good, but it's obviously not.

I know there's a shift delay TSB for the 45RFE, but what about my 48? Anyone ever have this issue with theirs? Must take 3-5 seconds for it to go anywhere in the morning. It'll actually do it after work sometimes too, but not as often.

 

If you are talking about putting it in gear and it does not move right away, that is probably the drain back valve in the cooler line leaking leaking back and draining the TC. Fluid does not circulate in park and it won't charge the TC until you take it out of park. Put it in neutral for a minute or so before you take off and it should work fine. If not there are other problems.

If you are talking about a lazy shift out of first gear that could be governor solenoid and/or governor pressure sensor.

 

Yeah that's the problem with it alright.

Isn't there a fix for this though?

Putting it in nuetral, waiting for it to fill, then moving it back into reverse does prevent it, but is all that unessisary shifting and waiting around really right? Come on...that's bunk.

The TSB's are for the 45re and not the 48re, but I'm sure as I can be it's the same problem. Really was hoping someone has a fix for it.

I found a site showing customer satisfaction notification E16 - tranny cooler return filter, but no TSB number. What do I tell the dealer to make them perform this?

 

Mine never does that.

 

Does it have a slight shutter on launch or take off from a light regardless of how hard or light the take off is? Not sure if that's normal or not either.

 

No it does not.

 

Yeah see. Mines goofy...I'm sure of it more and more.

 

Yes there is a fix. Replace the manual valve and pressure regulator valve in the VB with Sonnax parts and th eproblem is gone. You can then gut the drain back valve for better flow thru the cooler plus you will have flow in parl with the new valves.

While your at it, turn the line pressure up a bit and replace the gov solenoid and pressure transducer with after market parts and your shuttle shift, if you have it, should dissappear.

 

A lot of you guys on the forum have the luxury of bottomless pockets. The typical answer you often get around here is to throw money at the problem. Must be nice to be able to endlessly build custom trucks and upgrade parts with one mile on the clock, but let me rephrase the question. What's the fix that Dodge should do - as I already paid for a truck to work properly once already.

 

If you haven't figured it out yet, the dealer is not going to fix it because it is not a problem to them. Just get that striaght right now and move on.

If you want it fixed so it works right you will have to do it yourself or hire it done. Same as any other less than adequate OEM piece, its on your dime or live with it. Not saying its right, not defending DC's practices, its just the way it is.

See my previous post for what you need to fix it. The gov pieces are already done so you really need 2 valves at around $100 and a line pressure tweak. That SHOULD fix it but every one of these engines and trucks reacts a bit differently so keep that in mind. Good luck with whatever you decide.

 

We'll see what they say about it this morning. It does it after sitting over night and they wanted to keep it. Actually I insisted too. I don't want it back till they have it fix, or at least tell me they know what causes it but they're not going to do anything about it. If I get in a new one off the lot and it doesn't do it...then it ain't right. Not with 9500 miles on it. If it's a defective design, then they can just keep swapping the parts out till the warrenty is up. It started this shortly after being new. So that's alot of swapping.

 

Is it possible it's a cold fluid issue? Not warmed up enough.

 

Cold fluid, perhaps, but it can idle all day, and still do it. So it's not a cold engine. I'm sure cold fluid doesn't flow as well and that's the reason it takes even longer in cold weather to get into gear.
