Why does my Lincoln LS Shift hard
I have a 2005 Lincoln LS and the car seems to shift hard, during all typed of driving. It has been doing this since I purchased the car and I have had it looked at by the dealer on several occassions, each time they told me they could not find and problems with it. has anyone else had this problem, if so what was wrong with it. Any advice would help. My LS is the Sport with the V8.
The dealer isn't going to help you with little issues like this. See if you can find a local transmission shop, not a big name place, get some feedback on their work. Ask them to diagnose the trans for you. I don't think you need a new trans, try to sound informed and tell them you think the Transmission Pressure Control Solenoid Pack needs to be replaced. This seems to be a common issue on the transmission you have. There are 3 pressure control solenoids & 4 shift solenoids in one plastic part ,made by Bosch. You remove the trans pan,the gasket is reuseable silicone You remove the filter, You remove approx 7 -- T30 bolts, holding the solenoid pack & one 10mm electrical connector bolt. HPN-9L2Z7G391A about $400 for the part and add on labor. Add in some new Mercon V and filter kit and your good to go.
I have had that problem with my 2005 also. It's because it has an electronic transmission for faster shifts, but it isn't very refined. Mine became smoother in normal driving after adding fluid, my dealer did it.
is it an auto ?! if yes have the transmission oil been changed from the time u bought it ! if not replace the old oil 70 % of all the auto tranny problems r solved by this because transmission oil too have a life so they start to become thick and clog the valve control body of the tranny system
My 2005 has started this too. I am going to have the trans serviced. Then change the control solenoid. Thank you all for the info. I love my LS. I am only 5'4'' so it fits me well. Mr ROC
