I bought my Impala 4 years ago,year later the tranny acts up..slipping,common rebuild problems..Had it rebuilt..Ran great,shifted like it suppose to..Month ago,it got hard to move the shift lever.removed the cable got one from a recycle shop..still no help..tried to shift lever on the tranny,it wont hardly budge..Took it back to the shop that did it the first time..He says hes never seen a tranny do that..hes gotta take it appart and see whats going on..He says it might need a new case and he might have one laying around...His total rebuild cost is $1000..I really dont have the money but its better than buying a different car with maybe different problems..Anyone heard of the linkage inside the tranny getting bent or rubbing against somethin?Any clues?It drives great,shifts fine...Thanks in advance..
