I don't think my gears are shifting, and my transmission fluid is fine, what else could it be.
I have a 94 mercury grand marquis,
and when I accelerate the car shakes
and it doesn't seem its going into first
gear like it should. Its an automatic.
Could be internal to the transmission like the torque convertor or one of your motor/trans mounts are broken. Have it looked at by a reputable mechanic.
Probably your trans, but try Lucas Xmission additive, sometimes it does miracles.Can't hurt. How long since you changed the fluid and filter?
I'm having same issue, 94 grand marquis ls, slips on occasion going 30 up to 40. Has to be first gear accelerating, going to try Lucas anti-slip today. Any thoughts on the front pump failing to create enough pressure? Fluid is still perfect full after flush and replace filter/fluid at 150ish thousand now at 161872.
