94 z28 tranny problems, car running sluggish
i need some help in figuring out what the problem might be with my tranny. just purchased the car and it wasnt running correctly, after many checks it appeared that the catalytic was the problem. now the engine revs and sounds much better than before. went to drive it around the block for the first time and it ran sluggish . it had no power., I shifted from drive to reverse it didnt hook then i went from park to reverse and it hooked. it feels as if the torque converter is constantly on. Any advise , thanks

the previous owner had replaced fuel filter, fuel pump, spark plugs, water pump, opti cover and rotor, opti was replaced three years ago. when i purchased the car it didnt run. it sounded like the MAS was bad, but after several chks the cat seemed to be the problem. currently the cat is completely gutted out. the car idles now and revs with no problem, big difference. when i took it out yesterday around the block, it felt sluggish as if its on a higher gear. i gunned it one time and it responded like it should for a few seconds. the tranny fluid looked good. i chked it today, the engine was cold though. i have some codes to chk will ask neighbor for scanner. the car has 114,000 miles. i was thinking of replacing filter and fluid on tranny. do you think its in limp mode or a bad solenoid. is there a fuse for the voltage for the tranny. thanks

If the lock up clutch in the converter is stuck on, the car will stall as soon as you put it in gear. Can you feel the transmission shifting through all 4 forward gears?

just took car for another run, the tranny shift gears. i think i assumed the tranny was causing the car to run sluggish when now i think the tranny is ok what i did notice is when i shift to drive from park there is no positive movement.also when i put it to park from drive it appears like it didnt lock and tried again and it locked. when it shifts gears you cant hardly feel it. you know the feeling when you place the car in drive you feel the car wanting to move forward, well this one doesnt have that. I think my engine needs more tuning. thanks. i appreciate any suggestions and thank you for your time and input.
