transmission over temp light comes on
on interstate the car slows down and jerks alot, i have not have a spark plug change in
over 5years. do i need a tune up.
Transmission light is not related to your spark plugs. Todays cars get close to 100K on the plugs before replacing. Since you light is on, you'll need to scan the car for the codes to find out what the issue us with your transmission. Could be a sensor, solenoid or something internal to the transmission that needs replacing.
