Hey Guys,

I have an 04 Crossfire with 35,XXX miles on it. Last week i was driving home and noticed the car was stuck in gear (autostick wouldn't work either), so i got off the HWY and turned the car off restart and everything thing is fine. This morning I drive to work and all is dandy I get off the HWY and notice the car is stuck in a high gear, park the car go work blah blah. So I go to get a coffee in the afternoon and the car is stuck in 1st autostick wont work. I started my crawl home and on the way stopped to get some ATF, so i put a liter in still does not solve the problem.

Anyways I have a check engine light now and I'm going to bring it in but it'll have to wait until the weekend... Any ideas on what this could be?

Cheers,

 

it may be low on fluid, but the dealer has the dip stick, your tranny fill cap is sealed. I did have mine stuck in 3 (limp mode) when i was playing with the rear end it would go 1 then 2 then 3 then stay there. jim

 

I put a liter of ATF in, did nothing to solve the problem

 

It seems on these little cars that all roads lead to Rome and the ECU. Drat.

 

So I found out my wife filled the car with 87 octane, you think this could be causing the car to into limp home mode?

 

Don't believe this to be the problem ... a couple of forum members have opted to run 87 octane and I've heard or seen NO adverse issues with running the lower octane fuel. But that's a whole nutter thread ...

 

Let us know what the code is. We can go from there.
My Transmission Control Module is bad and the coupe is in limp mode (2nd gear only).

 

I was talking to my buddy who is a MB mechanic, he had a guesstimate that the Tran Control Mod was upwards of $1000. Really hoping its something minor. Bringing it in on Friday to have the code read.

I'll let you know

 

Local dealer wants $548 for the TCM. Mine is being replaced under warranty but the TCM is on indefinate back order. No telling when the part will be in.

If the TCM turns out to be the problem I have a TCM for a NA XF.


UPDATE: TCM was SOLD to another member.

 

Any answers on this yet? My 05 did the same thing yesterday...stuck in high gear and couldn't shift into anything else with the autostick. Drove down the road, stopped at a light, and everything worked fine when I took off. I had been shifting manualy right before this happened.

 

DJ, no fix for this module I take it.....

 

Anyone who sticks more oil in their transmission and then expects to get warranty work done may be sadly disappointed.
The dealership may use that as an excuse to avoid the warranty work.
They may say it was overfilled and that caused the problem, you would then be obliged to prove what came first the oil fill or the transmission problem, good luck on that.
Remember that a lot more paperwork is required for warranty work and they get paid less per hour for it. Chrysler has to OK warranty payments, it is much easier and financially beneficial for them to swipe your credit card. $$$$$$$$$$

 

The code coming up was P0715 Turbine/Speed Sensor, so I had a friend (MB mechanic) replace the electric plate (AT oil, electric plate & new filter = $312) but he had a cheap OBDII scanner and it wouldn't remove the code. Going to go have the code removed today.

Anyone know if I will need to have Transmission Adaptation after replacing the electric plate? or should the car be able to relearn the gears on its own?

 

Car is out of warranty, wasn't worried about "voiding" anything

 

Gears are controlled by the TCM. The "electric plate" is nothing more than electrical wire runs and changing it or the TCM does not require adaptation. (does include the speed sensor also)

Been there done that.

 

So would it make sense that the car would stay stuck in limp home mode until the code has been removed even though the faulty sensor was replaced? Or do you think i have another problem?

I appreciate your help!

 

Why was the electric plate replaced?

 

Code P0715 came up and my friend said its a common problem with that tranny. The speed sensor was on the new electric plate.

My thought was that once the problem was fixed it would automatically clear the code. Scanner kept comming up "pending"

 

FWIW, not talking about the tranny, I usually run 87 Octane fuel. No knock, no degradation in mileage or performance that I can tell at all, so fuel is the last thing I would be concerned with. Somewhere along the way, your car is merely in limp mode, and my bet would be the TCM.

 

Why would think this is TCM related? The code showing states input speed sensor:

(P0715) INPUT SENSOR MISMATCH . . . . . . . .21-90
(P0715) INPUT SENSOR OVERSPEED . . . . . . . .21-94
(P0715) N2 INPUT SPEED SENSOR
CIRCUIT. . . . . . . . . . . . . . . . . . . . . . . . . . . .21-97
(P0715) N3 INPUT SPEED SENSOR
CIRCUIT . . . . . . . . . . . . . . . . . . . . . . . . . .21-103


Everything points speed sensor, I had the electric plate replaced (which included a new speed sensor)
