Hi All - took my new Mach 1 to Summit Point main this weekend with my son. The car ran well, though it needs some work to truly go fast.
I ran into an issue I didn't expect, and wanted to ask if anyone else has seen this. After about 10-15 minutes at speed, I got the dreaded Rear Axle overheating error. Looking at the gauge and it's close to 300 - this was on a ~90 degree day. The car is stock, so I plan on changing the diff fluid to 75w140 soon, but has anyone else seen this with the GT350 or GT500?
This car is supposed to be running the diff cooler from those cars, so the overheating issue was completely unexpected. I'm hoping a simple fluid change will fix it, but wanted to find out if people had to go to more extreme measures for track cars?
I've read lots of horror stories about folks without a diff cooler, but most with the cooler seemed to be fine. I was driving my friend's 350R on track at speed and it was fine as well.
