Hi Dodge Fans!

I've had my '06 1500 Hemi Quad Cab since 2007, bought it from Maroone Dodge in Pembrook Pines, Miami, and shipped it across to the UK.

It's an awesome bit of kit and a love it! Looks huge on our roads in the UK!!

Anyway, whilst the mileage isn't huge I am having a couple of issues with the auto transmission. I wonder if anyone has a workshop manual for it?

The label has the following on it:
TITTJ194520117.
P52119452AD RFE

It's fitted to a 2006 Dodge Ram 1500 Quad Cab 5.7V8 Hemi

I have a code reader and its displaying the following:
P0700
P0750

Any help would be gratefully received.

Many Thanks,
Matt

 

First of all welcome to the forum!

Your codes are as you said for transmission and this is what they mean:
P0700 Transmission Control System Malfunction
P0750 Shift Solenoid A Malfunction

and you can download service manual here:

What are the symptoms? Maybe if you tell us what it is doing we can get you started in the correct direction!

 

Hey, thanks for the replay and useful links!!


The problem is as follows:
Since the fault codes have appeared the truck is in a limp home mode, only giving about 150-200hp but still drivable, until recently. Over drive and haul mode didn't work, nor did the kick down switch under the accel pedal.

When I was last able to drive it, coming along a dual carriageway I lost all drive, the engine would just rev high without the gearbox transmitting the drive to the prop shaft. Now it would seem when the vehicle is cold I can just about move it, but after more than 2 or 3 minutes of driving I loose all drive again.

Any ideas would be great, I need to get my truck back on the road, I miss it dearly!!

Thanks you,
Matt

 

Matt....you've obviously checked the fluid levels in the transmission??
It should be done when the fluids hot and in idle from memory. It states this on the dip stick. There's two sets of two small holes on the dipstick. One for hot and one set for cold. The fluid should be between the two small holes in either hot or cold condition, after you have worked the gears through all positions for at least two seconds.
Did the fluid smell burned or tinted with dark sooty deposits??
Do you know when the transmission last had new fluids and filters?
If none of the above, you need to take it to a transmission shop for service bud.

Hi Al,

Thanks for the reply, yes checked fluid levels, but not quite as say (fluids hot and in idle) this will be a bit of a problem now because the truck doesn't move much so getting it warm will be difficult, I can at least try it in idle rather than engine off.

The fluid didn't smell burnt and had no sooty deposits, actually looked ok.

I'm not sure when it last had fluid and filter change so ill be sure to get this done ASAP anyway, but I'll check the fluid levels again in the way you mention.

Do you think the shift solenoid/s could be ok then and is it possible this may be resolved with a service?

Thanks again for all your help,
Matt

 

You should probably try to find a shop to get a transmission scanner on it!

 

Well these transmissions are pretty complex being fully electronic and all. I doubt very much if a simple service will fix your problem.
You need an OBD scanner and get the full codes for what your transmission is setting as error codes bud as Busdriver9 suggests.
I do know that 2nd and overdrive clutch (they are one and the same in this tranny) very commonly burn up/wear out. But it could literally be anything.
A Chrysler dealer where you live will be able to scan your truck for you as they repair these transmissions here in the UK as they are fitted to some Chryslers over here.

Queston to our to our fellow American members......do the ChryslerC300 have the 545RFE boxes in them?? If so Matt, they sell them over here so the dealers have to support them.

One thing you could try, is to reset your computer by taking the battery positive off and leaving all your lights on etc, to drain away any residual currents left in the system for 15 mins or so.
Make sure you have codes for your radio etc before you disconnect the battery.
Reconnect your battery back up making sure you've turned everything off first. Then start the truck It will possibly idle rough for a few mins whilst it relearns fuel trims etc. Do not put your foot on the gas when you first restart ok. Let it do it's thing and it will settle.
It may pop out of limp mode for a while or again immediately throw you codes again.
It's worth a try mate.
Al.

 

Got a little update for you all, I took the truck into a local gearbox specialist who has stripped the box and found it to be in a pretty bad way. Anyway, long story short its had a full rebuild, including replacing the valve block, and the fault remained! traced it back to the ECU,ordered a new one from the states which should arrive on Wednesday, so hopefully it'll be running again by the end of the week!

Thanks for all your help and suggestions chaps.

Matt

 

boat buoy, I strongly suggest getting the "FSM" factory service manual for your truck, especially being on the other side of the pond.
The FSM will have the specific trouble codes in it for your year truck, plus it will give you a good idea whether to fix it yourself, or get it to someone that can, plus all the regular service stuff.
