Does the 2010 S/C not automatically switch into the next gear on redline or it there something wrong with my vehicle? When I put it into first gear manually and accelerate, it gets up to redline real quick and then I get extreme hesitation and it just about comes to a screeching stop unless I manually switch into 2nd gear. By then the SRT8 next to me was long gone!
Also if I am cruising along at say 100km/hr (in Drive mode) and down shift using the paddleshifts, sometimes it will go into 4th gear and then I have to paddle shift down again into 3rd to get some acceleration. However other times (Perhaps in Sport mode) it will downshift drastically into 2nd gear and again just about stop like I slammed on the brakes, until I paddleshift into a higher gear!
Whether I intentionally or accidentally put the vehicle in a gear too low for the speed I'm going, the electronics should automatically bump it up a gear to prevent both engine and transmission damage. My S/C does not seem to do this!
Of all the other SUV's in the family (ML63 AMG, Cayenne S and X5 5.0) none of them will get extreme constipation when redlined in 1st gear. They all automatically switch into 2nd. And neither will they let me switch into 2nd gear at 100km/hr and get extreme constipation! They all automatically switch into 3rd.
Wonder if my S/C needs a transmission software update...
