Hi, I'm Greg (Indy-Tech).Welcome to JustAnswer. I'm reviewing your question now, and will post back with your reply ASAP.Rgds Greg.
One question so we are on the same page .
What diagnostic checks did you do to confirm a bad transmission .
Was no diagnostic scan tool hooked up to check for transmission malfunction codes .
Hi Bernard .
I fear that you may have changed a good gearbox for nothing .
As for this issue is a update TCM reprogram to sort out this problem .
IF was already done and still issue then could an issue with the transmission input and output controls .
You will have to have the car hooked up and checked for engine and transmission management
From the malfunction codes you will then know what has been causing you this issue .
Very common for this would be a TSB for the update reflash/reprogram .
Your dealer will have information on this issue and will advise what is best done .
Sad the Transmission shop did not check for TSB for this concern first...
Need further assistance with this issue then please get back to me with the reply box below .After rating there is no further cost for any other question relating this issue .Kind regards Greg
Okay if no codes have him check with the dealer for any TSB concerning this issue they maybe a reflash to
rectify this issue .
Did you at all recheck for transmission malfunction codes .
Has any warning light come on at all when the engine is running .
Oh which engine do you have in the Coupe 1.6. 2.0L or the 2.7L
What was the codes Engine management codes can affect transmission operation .
Thank you Bernard will look out for your response with the codes .
No warranty on the box you changed ??
Could be it as your mechanic said .
Don't think driving it will change anything .
See if you can get hooked up and let me know what the codes are for the engine .
Same transmission code come back.
