Hello gents...
So, I had issues with my older transmission. It felt like it only had 2nd and 3rd gear and started from a stop very slow. I had the blinking transmission light as well.
I swapped in a used transmission I bought using my original torque converter. Now the transmission light stays on and the car chirps like crazy. Please see the video and see if you can give me insight on what may be wrong. Thanks a ton in advanced.
