2008 Mercury Mariner throttle control powertrain light comes on, transmission cannot go into gear properly, it stops at 4000 rpm, and it struggles to go at higher speeds,.
I have been having problems with my 2008 Mercury Mariner transmission during the winter of 2010 and continuing. When the engine is cold the transmission slips. When I accelerate the engine revs and then slams into gear. Furthermore, while sitting at a stop sign or traffic light with my foot on the brake, the engine will rev up then shift in another gear then when taking off the vehicle slams into gear. On more than one occasion, the vehicle will cut off completely when idling at a traffic light. The revving and engine cutting off is getting worse when the engine is cold or warm.
