Other Homework Help

Hello, I am trying to help a friend with a problem,he has a 2002 Chevy impala 3.8L. The car was running just fine got a transmission service then about 2 months later he comes out to go to work and puts it into gear and nothing. Revs the engine and hit goes into gear very hard. once in gear drives fine goes through all the gears just fine. once the car is warmed up it will go into gear fine just from a cold start it takes a second to go into gear and it hits VERY HARD. I am very machanically inclined but with auto trans the only thing i now is to replace them, he just does have the money to do it in a shop and i really dont want to replace the transmission on the ground ( pain in the a$$) ive been reading up on these cars and alot of people are talkin about cleaning or replacing the valve body and/or Torque Converter clutch solenoid. So my question is could this be a problem.. done want to do the transmission if i dont have too.. plus hes not keepin the car pass jan. 1
