Default 07 sebring surging

Yes an 07 sebring with only 500 miles is surging.Anywherebetween 40 to 60mph it surges 200rpm when using the accelerator.It stops surging when you set cruise. The idle is steady. Any ideas? I thought maybe the accelerator peddle sensor. Oh well it does go in in a couple days. No check engine light.

If you are talking about TCC engagement, yes mine did that as well. Many of the newer Chryslers I have owned do this. They started a TCC break in period that would last about 500 miles a few years back. I believe they discontinued it, but recently I think it has been reinstated. It is supposed to give the new converter time to "break in" for the lockup clutch.

Inside the torque converter the clutch is bonded with glue. They tend to rip the glue backing apart after many thousands of miles. In an effort to ease the strain on the clutch in the beginning, the TCC is not fully applied. You should notice it disappearing pretty soon. Everytime the computer is reset it "could" reset the TCC break in period though.

Again, I am stating facts from earlier models and I am not 100% positive that this is your issue. Hope this helps.

SYMPTOM/CONDITION:
The vehicle operator may experience one or more of the following symptoms:
1. Transmission Shudder - 42RLE All, 41TE CS/JS, 62TE CS/JS
a. This condition can only occur after the vehicle has been driven and the torque
convertor is past the break in period. Torque Converter break in can be confirmed
with the StarSCAN®.
b. If experienced, the shudder may occur when the transmission temperature is
between 38° C and 54° C (100° F and 130° F) during steady state driving with the
torque convertor in partial lock (EMCC) operation. The shudder feels like the vehicle
is being driven over rumble strips.
2. Torque Converter Pull In Bump - 41TE JS, 62TE CS/JS
a. This condition can occur due to abrupt torque converter clutch engagement during
EMCC initialization.
3. DTC P0732 - Gear Ratio Error in 2nd Gear - 62TE CS
a. The MIL may or may not be lit (2 trip fault).
b. Limp In will occur when this fault is set.
c. This is an intermittent condition and cannot be duplicated. If the fault can be
duplicated, other conditions exist and further investigation will be required.
4. Shift Quality Improvements - 62TE CS
a. Rapid Decel Coastdown Stumble.
b. Low Speed 3-2 Kickdown Harshness.
c. 4-5 and/or 5-6 upshift flare bump.

No i dont think it has anything to do with the torque converter. This happens after you are in high gear and converter is locked. Engine will surge by 200 rpms on level road.The tach will climb 200rpms then right away drop 200rpms and goes on continuisly until you press further on pedal. It stops if you set the cruise.

the converter is high gear my friend its basicly a 1:1 gear ratio with lockup. It will go in and out based off road and pedal condition.

Again this happens after the converter locks up and the road is level and you hold the pedel completlysteady. I dont know how to explain it any clearer. The engine revs up and down by 200rpm very quickly. Almost like you are pumping the accelerator.Cannot feel any shifting at all. But if you set the cruise its fine. Still thinking the apps.

if it was the apps u would get a code there is 2 apps in the throtle body and 2 in the pedal
if one set was bad then the other would see the miss match in volts and set a code and go into limp in as far as the tranny. The tsb above should take care of the tranny surging with an updated software package on TCC.

Ok why would the surging stop if you quickly set the cruise when its surging? Seems it only does this when your foot is on the pedal.

The 200 rpm up/down was exactly what mine was doing. When I used the cruise it STILL did it though. This is the TCC cycling. This is not the first time that MOPAR has had this issue with it's converters/programming. Not a big thing if you get it corrected.

I am planning to take mine in shortly to get the flash, even though it stopped doing it for the last 1000 or so miles.

Thanks for the TSB. Kinda figured they might be putting that one out.
