Actually I must be the luckiest person to own 2000 TL.
The only thing is if I do not wait for transmission to engage completely to drive, the car stalls.
The only I don't like is the driver's seat. For some reason, it's not comfortable at all.
The ransmission always seems to hesitating, however it works. My shifter in winter time requires high effort to shift out of park to drive.
I have news for your, your transmission is going to go south in the next few thousand miles. I have a 1999 and the car has 150K miles on it. When you think about if your car is like mine, $3,000 for a transmission isn't bad if its the only repair you have ever had to have done!
