2007 Mercury Grand Marquis Q&A

2007 Mercury Grand Marquis Question: Between 55-70 mph only, feels like transmission slips.

37,000 miles on car, no increase in rpms, only "slips" for about 1 second. -
Answer 1
There is a history of front pump failures on those, hope it's not yours. -
Answer 2
If it were slipping rpm would increase, even for that 1 second! Scanner can actually display data to show slippage. Have it tested. -
