what should I do? I attempted to change and flush my ATF in my 2005 corrola. Got a filter kit with gasket, 7 quarts of T-IV compatible Castorl ATF and got to work. I drained the pan and took it off to find that, both the gasket and the filter the auto parts store gave me doesn't fit. So I cleaned the pan and the outside of the old filter with brake cleaner, dried them thoroughly and put them back on with a thin coat of liquid gasket on the old gasket. Thats disaster number one. Disconected the tranny lines to the radiator and pointed them to a bucket. Added fluid had a friend start the car, and started dumping fluid in to replace what was coming out. But it wouldn't fill fast enough to compensate for what was being pumped out and the fluid started sputtering which told me it emptied the pan and was sucking air. However the fluid ran bright red before it started coughing so the old stuff got out. Reattached the hoses tried to re fill the AT to find I was about 3/4 a quart low. I test drove it and it ran/shifted fine. Can I drive it to the store (30 miles away) to get more fluid or should I have a friend take me? Should I try and return the mis-sized part i was sold and demand they give me a few quarts of free fluid since I will have to drain the pan to replace the filter screen? Or am I fine just using the old filter and gasket (as long as it doesn't leak)? Also, did I ruin my tranny by letting it suck air? Thanks in advance!
