New Transmission - problems abound

[Jason Bowles]

I just spent $3500.00 to have a new transmission put into my SHO. Best part is it doesn't shift correctly and when I took it back they said it shifted just fine and gave it back to me saying there's nothing wrong.

So I drive the car to Idaho and back and while in traffic with the stop and go stop and go BS when I hit the throttle a little bit and let go the tranny would hesitate and hard shift from 1st to 2nd every damn time for the 2 hour traffic jam. I havent taken it back to them again yet and I would like to know the forums insight before I go back to them and tell'em to FU.. Off and give me my money back.

The car is sending a continuous code of 122 -TPS, but it doesn't pull it KOEO or KOER. I'm guessing it's because I disconnected it as I did with the other sensors to clean them to see if it was a sensor problem. That's not it.

If the shop tells me it's ok again I'm contesting the charge on my credit card and getting my money back stating that I did not get the service I paid for and I know I will get the charge reversed.

My biggest problem is - The shop told me that this was brand new from the ford factory since this shop does not do rebuilds. Anyone know if that's a load of BS or not? It cost $2096.00 for the tranny and $1300 for labor. The Warranty if 5 years 75k miles.

Let me know your thoughts guys

Shift scheduling and line pressure is mainly a function of throttle position (TPS) and vehicle speed (VSS). With either of those signals missing or corrupted, the tranny will shift like crap.

Does your cruise control work? If not, they might have left the VSS disconnected or the sensor may be bad. Normally a disconnected sensor should fire a code, but I've seen situations where a bad sensor didn't. VSS sensors are not included with a Ford reman, they just swap it over from your old tranny to the new one during the R&R so if yours was already bad that could be a cause of your issue.

Explain your TPS code further. A hard code should show up both KOEO and KOER, but it must have shown up at least one or the other for you to have read the code. If you still have this code after clearing them, then you have a TPS issue you need to address. I'd start with a multimeter to see what voltages the TPS is providing across the range from closed throttle to wide open.

You should also check your TSS connection. Remove your drivers front tire and look above where the axle goes into the tranny. You'll see a little black sensor on the side of the tranny there; make sure there is a wire connected. I've left the TSS sensor disconnected a couple of times and that will also cause crappy shifting.

FWIW, did this place **** you up before ****** you? I bet a Ford dealer wouldn't have charged you that much.

i have to agree with chirs, that is awfully expensive, as far as the TPS, i am having the same problem myself, i am going to get a new one and if that dosn't fix it i am going to have to tear into it deaper, i am getting 0 volts at idle, havn't tried anything else with it yet. i'm a little ****** off at my car at the moment, just put my tranny in and now i have MORE fun to deal with, yes it never ends, sigh.
