2002 Impala-trans. shift hard
Was wondering if anyone knew why the transmission would start shifting hard. The car has over 200 k miles, but runs great. It just recently started shifting hard.

Re: 2002 Impala-trans. shift hard
If a transmission code is set, the code may force the PCM to run with FULL LINE pressure, causing harsh shifts....
Check for codes.... Check fluid level and condition..... Last transmission service? |
