2006 Lincoln LS V8 98k miles. I replaced my transmission solenoid pack, valve body, filter and fluid a few months back because i was having some hard shifts and stuff like that. Everything i replaced were OEM except the solenoid pack. shifted a lot better afterwards. although not perfect. It mainly fixed the harsh engagement in reverse. recently it’s been shifting a little stiffer especially when the weather is cold and the car is cold. when i brake to where i’m slow enough that the car downshifts into first, then i let off the brake and try to accelerate the engine revs and then the car jerks a short while after. almost as if it wasn’t engaged in any gear. along with that the trans slips every once in awhile when cruising around 50mph. harsh engagement when i put it in drive etc. thoughts.
