Guy guys, last time I posted in February I was having various codes issues , restricted performance and trans fault error codes after putting the pedal to the metal. The car had seem to have missed a shift or miss fired. I believed I did some serious damaged to the trans because at a stop light the trans was trying to shift with hard slams and going into a neutral during acceleration. I took it to a trans shop and they didn't know if it was the trans or the ECU. So I ended up taking it to the dealer and all they told me is it needed a new trans.Both shops told me 3 -7K to repair. After picking it up from the dealer and driving it to work I notice the engine was miss firing, an at this time all kinds of restricted performance, Trans fault codes reappeared. I Ended up taking it to my local Jaguar independent shop that worked on my car before. He stated that he had a bulletin that talked about bad ign coils will cause these symptoms, sure enough a few hours later, two coils and two plugs and the car drives like a dream.I was ready to dump it and buy a new car couldn't believe this is all it was. $531.00 out the door.

 

In the past other people have reported transmission faults due to engine misfiring.

Glad you got it fixed.

 

Thanks Meirion 1.

 

It's because to provide smooth shifts etc the trans & engine co-operate. Can't do it right if there's an engine issue.

Hooray for your indy and boo for the dealers.
