Lately, I've been having an issue in my 01 SPI automatic where sometimes during the first 15-20 minutes of driving I'll start from a stop and the car won't accelerate normally (far slower) and there's kind of a grinding noise and a vibration. If I lift and then resume normal acceleration it goes away. Any ideas what this is? Is my trans grenaded? If it's not transmission, what should I check, and is this a fatal issue? Once the car is 100% warm there are no issues and 3/4 starts in those first few minutes are normal, but there's always one or two lately that show those symptoms described above. If there's any way to save my MkI I'd like to do it, and if it's time to move on I'd like to start looking with certainty that it's the right choice.
