02 wrx AT slip
I am a new owner of an 02 WRX and sadly although i love the car it has been nothing but a headache. i bought the car about 3 weeks ago, (and i have bought many cars before and know what to look for), bt the subaru pulled the wool over my eyes. i test drove the car and it didnt have any problems that i could detect, no engine knock, no tranny problems, no smoke, tons of power. after signing the check and handing to the dealer i was on my way home.... i made it about 3.5 MI down the road and it sounded like a rock was tumbling inside of my engine. after a lil research i concluded that it was a spun bearing. my suspicion was confirmed after paying a mechanic 3500 to do an engine swap. so last saturday i got my car back and i notice the transmission sliping under hard acceleration. bt it wasnt very bad so i thought nothing of it but maybe low fluid level. on sunday i didnt drive the car at all. on monday i got in it to drive to work and it backed out of the parking space perfectly fine. when i put it in drive it shifted into gear fine but would just rev up and bearly crawl to 5 mph when at 5k rpm. no grinding sounds or anything it just wouldnt go anywhere. I checked the fluid level and it was at full, although the fluid was a goldish-brown color (and not red like tranny fluid should look like). before the engine swap the tranny didnt show any signs of slipping. so now that you have my back story this are the questions that i am asking myself and would apperciate any help i can get from yall.
*could this be due to loss of fluid in the torque converter?
*could this be due to the engine not being properly installed into the tranny?
*could it just be that i bought a car with a bad motor and tranny, and since the tranny never did this before the engine swap, is it possible that it just decided to take a complete shit at the worst possible time.
If there is anyone out there that has had a similar problem with thier WRX could you please give me some advice. Thanks and it will be much appreciated.
