Just a quick heads up. I had a grind in my 3rd gear when I’d shift quickly ever since I got my truck a month ago. If I’d push in the clutch and wait a second to shift there was no grind. I’m guessing the synchro is going out? Today i changed my trans fluid and refilled with 5 quarts of REDLINE MT-85 through the top of the shifter hole. After the change I TRIED to get it to grind but it wouldn’t. I’m guessing the MT-85 is doing some good in there. The price was the same as the Amsoil that everyone uses. Not sure if anyone else has had the same results but wanted to give the heads up
