Report: Harsh or Delayed Shifting of Automatic Transmission
Mercury Montego Problem
Drive Train Affected: AWD
Average Mileage: 70,791 mi (54,540 mi - 113,000 mi)
The automatic transmission may develop shifting concerns. On lower mileage vehicles, upgrading the software in the powertrain control module (PCM) and the transmission control module (TCM) may correct the problem. As the mileage increases, internal transmission damage can occur. Repairs could involve replacement of the valve body or a complete transmission rebuild. Whenever major transmission repairs are made, it is important to be sure the PCM and the TCM have the latest software updates to help prevent these issues from reoccurring.
2005 Mercury Montego: 45,000 miles needs new transmission and already replaced engine mounts...piece of crap - no one will help. No assistance from Ford, Mercury, filed claim with NHTSA...they responded they did not have enough cases...I am going to find enough cases...I am going to contact every internet site, media outlet, etc..until someone takes care of this!

slow and raking sound in the transmission .. this happened for a few weeks before the tool light came on however, it only does it when the vehicle engine is hot from 1 hr use or hot weather and 1 hr. use. The company should call these defects as as a recall.

Harsh down shifting, "hunting" find overdrive, and then will have rpm spike with no acceleration.
Planetary Gear Assembly shirred off and now the whole transmission has to be rebuilt or replaced.

Problem: Sometimes has a ruff shift when starting first thing in am. Or, if it has been sitting for a while. Usually if it has been driven a few miles it works just fine. I haven't had anything done with it yet.
