Transmission question

I purchased a 2013 police interceptor sedan back in april from a auction. The car has 152k miles and was hit in the front. In the accident something broke part of the plastic transmission filler neck off but not enough to where it was leaking fluid. I put the filler cap on and slapped a piece of duct tape over the open area. I finally got the car rebuilt, painted, insured and tagged. What I at first thought was a engine miss I now am thinking it could be a transmission slip. It is only noticeable when the car changes into 3rd and 4th gear with normal acceleration. It seems to not be present under hard acceleration or in any other gears. It feels like a jerking motion when its present. Does this sound like a terminal transmission issue? Any input is appreciated.

Does it do it while cruising or just during shifts? Is the fluid level good?

It does it while cruising in 3rd and 4th gears. It seems to shift fine. Will check the fluid today and report back.

It’s probably a misfire or a torque converter problem then. Check Mode $06 misfire data next https://www.motor.com/magazinepdfs/072011_09.pdf

Torque converter shudder sounds possible. I know when I had a crown vic they said torque converter shudder would go away when the brake pedal was applied while driving. I tried depressing the brake pedal today while it was acting up and it did not make the problem go away. Not sure if that crown vic test works on the 2013 police interceptor though. There is a humming noise that appears around 45 mph that increases with rpm's. I remember the first time we started the car. It had been sitting for I am guessing a year it made a loud clunk and shut off immediately. The clunk sounded like it came from the torque converter area. After that it started right up and idled great. The car idles so quiet you can not hear it running. We just got the car insured and tagged so have only put about 50-60 miles on it so far. Other than the jerking and humming it drives great. Is it possible the torque converter could have gotten jammed up from the accident or from sitting?

I’ve heard the same thing about tapping the brake regarding the F150, I’m sure it would be the same. Check misfire data & fluid condition.

Checked the fluid this morning. It is at the full mark and has a light pinkish color. It is not the reddish pink that new fluid is but at least it is not brown. Checked for codes also. The CEL is not luminated but there is a P1299 code. Code says cylinder head overtemperature protection active. Could this mean the ECM may have shut down cylinders to protect from overheating? The temperature gauge reads normal temperature and always has.

Is the P1299 a current, pending or permanent code? If it's not current or pending, don't worry about it, it's just historical and to my knowledge can't be cleared (it just tells Ford techs that the engine may have overheated at some point in the past, which I believe they use for warranty claims - approve/deny).

Check Mode $06 misfire data while driving ideally when you can duplicate the issue, there will be misfire counts per cylinder. Coils can degraded but not yet failed enough to set a code. I've heard of this before on Fords. I do not recommend just replacing all the coils as a guess though. If you do replace coils at some point, go Ford/Motorcraft only.

You were right. The p1299 code is a permanent code and can not be erased. I Was able to find misfire test for components $ob on my scanner under special test. I took the car on about a 1 mile ride and all the cylinders tested ok with no misfires. I am leaning more and more towards thinking its a transmission or torque converter problem. I know where 2-2014 police interceptors are in a junk yard, both with around 24k miles on them. Someone has already taken the engines out of both and the transmissions are laying under the cars with the torque converters. I can get one of them for $68.+ a $30. core charge. That includes the torque converter. My car has the non turbo 3.5 and the cars in the junkyard had the 3.7. Will those be direct replacements for the one I have now? By the way, Thanks for all the help. Also while trying to find a way to check for misfires on my scanner I uncovered a p1124 code. Don't think it has anything to do with my troubles though.

Were you able to duplicate the jerking motion while watching the misfire counts? You want to watch the misfire counts as you duplicate the concern.

I'm not familiar with the P1124 code, it may be related. I see P1124 Throttle Position Sensor Out of Self-Test Range @ Ford OBD Codes.

I suppose if the signal from the throttle position sensor goes fubar it could cause some weird driveability issues...

I took the car to the Ford dealership my son used to work at. They gave me the employee rate to diagnose the problem. They only charged me $89.00. Turns out the car ran over something (probably in the accident) and damaged the transmission and the PTO. The dealership is working up a price to do the repairs, but I am sure I will end up doing them myself because of the cost. I thought the problem was the transmission because it only acted up in 3rd and 4th gears. Anyone know if a transmission and PTO from a 2014 police interceptor sedan AWD will work in a 2013 police interceptor sedan AWD? The only difference is the 2014 has a 3.7 and my car has a 3.5 non turbo. Thanks
