Well i finally got my car back today since it needed a new gas tank but now something else seems to be going wrong. I start out in 1st then shift to 2nd gear, say im goin 40km/h when i hit 2nd, but then when i push my foot all the way down to the floor the rpms start goin really high really fast but im goin so slow speed wise? Even say if im on the highway goin 100km/h in 5th gear, then i have to pass someone and downshift to 4th gear, right when i get into 4th and pin it my rpms go really high but the car is almost doing the same speed as when i was in 5th? Im not to sure what this could be? comments would be greatly apprieciated 
my car is an 87 supra turbo.
