I'm ready to answer your KIA questions right now.

I need to ask you for more information.

What was the reason you replaced the transmission?

what is the problem you are having now with the transmission?

what is the mileage on the vehicle?

where there any trouble codes before replacing transmission?

have you tried a adaptive relearn of your transmission after replacement?

The same problem was the reason,

115,900 miles no codes nd installed a used transmission

Whet is an adaptive relearn (what's the procedure)
Expert:  FlatRate572 replied 5 years ago.

you said you new transmission is doing the same thing as the original transmission, but you never said what the transmission was doing,

was the transmission shifting hard?

not shifting at all?


adaptive relearn is as follows

disconnect battery for 30 seconds, reconnect battery, start engine, put shifter in position "D", for 5 seconds, then in position "N" for 5 seconds, then back to "D" 5 seconds...then back to "N" 5 seconds do this 5 times total.

then position "R" 5 seconds then position "N" 5 seconds, repeat this process 5 times,total.


If this does not work change anything, you may want to replace your transmission control module, 90% of the time, if transmission did not fix the problem, it was because the pcm was the fault.
