I know the location of the speed sensor. The problem is, it's not reachable from the side, even after removing the wheel. I don't have a lift. I need to know if there's another way to reach the passenger side of the transmission.Have you looked for 4T65E vehicle speed sensor location. Your check engine light is off?
It stalls mostly, but not entirely, while stopped. It also stalls sometimes while in motion, including while rolling out of the driveway while the engine is still cold (to perhaps anticipate your next question).So your first post states only city driving, does it stall as you come to a stop or at say 30 mph it can stall?
Does the stalling coincide with hitting a bump in the road?
It doesn't always still when I come to a stop. Usually, I come to a stop BECAUSE it stalls.No check engine light?
You have a lockup torque converter which should release when you come to a stop, if it doesn't the car stalls.
The other possibility is the throttle body or idle air control valve needs cleaning.
These items though dont tie in with the speedometer issue.
