Yep, makes sense, as this characteristic also applied to other Mustangs I've had in the past. With the viscosity of the fluid that is in the current transmission, I certainly understand how the cold would impact it. Thanks for sharing your past MT-82 experience.
Good to know. Since I'm in florida, and have a garage, this shouldn't be much of a problem.
Mine is doing this as well. The car I test drove did not do it.
I am getting the same issue. Granted my car also only has about 100 miles on it. Also I haven't experienced silky smooth shifts, but once again, it'll might take some getting used to and finding the correct shift points. My bucking seems to happen more when I am going over speed bumps or something like that and re-engage the clutch in first. Quite embarrasing when riding someone in the car, showing it off; but once again, every car has its quirks and it takes time to figure it out. Also my gears do grind sometimes when downshifting from higher gears to lower gears, like 5th to 3rd, or even going to 5th gear or 6th, but once again I might need to rev match. I'll figure it out. If that bucking doesn't go away by the end of the break in period, I'll probably check back on here to see what other drivers did or found out about it. Also my car is not a DD, so it might not be a huge deal , but one I will keep an eye on.
There were plenty of problems with the Tremec T3650 that is in your '05 when these first came available in later SN-95s (2000-2003). I actually had the Mexican-made T3650 in my '03 Mach entirely replaced within the first 2 years of ownership of that car. It took about 2 years before the manufacturing improved (2004 calendar year) such that fewer people were reporting grinding gears.
After reading some of the comments on shifting, I now let the revs drop first before shifting. Also I assume that the cold weather has some effect as well as well as the car not being broken in yet. I figured I can't quick shift this car like I did with my Acura. My 98 BMW 560 sport, kind of did the same thing. It wasn't a quick shift car and the clutch in it was crazy heavy. I do however like the clutch feel wayyyy better in this stang.
For the MT-82 Getrag gearbox Ford recommends QDC Dual Clutch Tranny Fluid with XL-18 Additive. This is part of a TSB that came out a few years earlier. From what I have heard, everyone who is using the QDC and the XL-18 additive is having better results but you must add the XL-18 to the mix and this is annotated not in the TSB but in the revised Transmission Lubrication charts as NOTE #6:doh:On a similar note, I just received my GT yesterday and I have had zero shift problems or clutch problems to date (other than the afore mentioned "Thump" when first engaging into First Gear). Getting used to the shift gate as well as how much (or little) pressure one has to exert on the gearshift itself seems to be a tactile memory or "Feel" type of muscle coordination exercise. Clutch throw-out is shorter than expected and I can almost heel-toe the clutch while shifting without missing a gear.
Correct...I asked my dealer's service manager about the XL-18 and he was totally in the dark about it...showed him the Transmission Lubrication Chart and he was stunned as the TSB said absolutely nothing about the additive. He said he was going to inform his entire staff as well as send a PM to Ford recommending a change to the TSB (told him that has probably been addressed ad nauseum but the more folks get the engineering staff's attention the better for all concerned in the long run). :gossip:
