I have a 2003 Ford Mustang gt that during cold weather has problems shifting from 1st to 2nd gear, it's almost as if I am not even pushing the clutch in. I have 700 miles left on my warranty and it will be many months before it is cold again to reproduce the problem for the dealer so I suppose I will be eating it on this unless Ford owns up to ip. After research on the NHTSA site I see many others are having the same problem and getting no results from the dealer.
In my 2003 Mustang gt with tremec tranny. . . Grinding type feeling going into second gear. Went to dealer, and they said feeling was normal,and it would go away,it has not. I only drive it once and a while but it is worse on colder days!!!.
There was a transmission problem. It was very difficult to shift gears, especially when the vehicle was cold. The consumer contacted the dealer, who stated that it was a cosmetic problem, and they were aware of it. However, the recall will not take place until the fourth quarter.
2003 Mustang mach 1 has had shifting problem since I bought it in sept 03. Ford supposedly has been aware of this problem for a year or two. They have yet to come out with a TSB. The car is difficult to shift, especially when temperature outside is cool. Because it sometimes takes 2 or 3 seconds (or more) to shift into the next gear the car is just coasting upon leaving a stoplight and I have almost been rearended numerous times because the trans won't allow quick enough shifts. Car only has about 3,500 adult driven miles, 2400 of which are highway. Many acquaintances have had this same complaint. Trans manufacturer (tremec) told people at 40th Mustang anniv that Ford was supposed to issue a TSB. It hasn't come to pass yet.
My 2003 Mustang gt with a manual transmission (5 speed), grinds when I go from first gear to second gear. This grinding goes away after the car is warm and is much worse in the winter and cold days. This is a complaint that almost every Mustang owner has and is documented well on websites such as stangnet. Net. The dealers never fix this problem and tell you that it is normal or is not reproduceable. Ford is not owning up to a problem with their car, is this something that NHTSA helps with or do I need to contact someone else? mike hamilton.
Concerns with a tr3650 manual transmission exhibiting clash/grinding sound during the first few miles of driving.
Grinding 2nd gear when shifting up from 1st gear. Much worse in cold temperatures. Down shift okay. Tremec 3650 transmission. Dealer states condition is normal.
Manual transmission in 2003 Ford Mustang gt shifts with great difficulty frm first gear to second gear. Sometimes, it has difficulty shifting from second gear to third gear. This situation makes the car dangerous as one may not be able to accelerate away from a possible collision due to the car slowing down while trying to get it into gear. Second gear will often "grind". Ford supposedly has a fix but will not be available 2-3 months.
Manual transmission series 3650 on 2003 Ford Mustangs grind and/or lock out upon shifting into 2nd gear as well as in to third as the problem continues.
Tremec 5 speed transmission has erratic performance when shifting gears. My research on this has indicated that there is a several year history of many cars with this transmission (mustand gt and cobra ) that have this problem. I have had the transmission replaced by Ford dealer once but with no difference and Ford consumer help line had yielded no results. This happens more frequently in winter when fluid is more viscous and blocking rings have been identified by dealer as potential cause. Has been happening contiuously since I have owned vehiclel for over a year and 28,000 miles.
