In the morning and cold my grand voyager does not go when I shift into driver. I have to hold on the gas pedal for about almost 10 second before it even moves and I was wondering what is wrong with it and what needs to be done to it. Thanks in advance for your advice and looking forward to hear from you.

Answers from the Automotive Experts

Amanda J. Pierce, MBA Sue Lee, Thank You for coming to askpatty with your concern. You may be experiencing delayed throttle response in cold weather due to the fact that FIrst, if this is fuel injected, locate, remove, and clean your IDLE AIR CONTROL VALVE. When this guy gets dirty it can cause hesitation. Clean your PCV valve, throttle plate, and throttle body, as well. Many later model cars get signals from the throttle body to shift the trans points. A failing or dirty engine sensor can "act" like a bad transmission. Also, try a good engine de-sludging chemical, like butyl cello-solve. Remove as much sludge as possible, and swear off regular engine oils in favor of the newer synthetic oils. These "synthetic oils DO remove sludge as you drive and promote better performance, fuel mileage, lower emissions, and even better trans shifting. They only need changing once a year or twice a year.

Laurie Sarno, Co-Owner at Super Girls Auto Hello Sue- 1st check your transmission fluid level ( which must be done when the car is running) - if it is low add fluid- also it could be a transmission filter issue- other than that it could be an issue with the transmission valve body or transmission pump- I would take it to a competent transmission shop & have them check it out- hope this helps, thanks Super Girls Auto.
