Just rolled over 20k
I I changed out to the rotella t6 last night and I don't think that has anything to do with this. I've had 2nd gear long gone for a while now.
Just got to my destination and it's slipping bad in 5th. That might be the t6 but I've lost 3rd and 4th gear. I can 1st no problem and if I baby it and hold the shifter back I can use 2nd for a little bit and then bang shift through 3-4 and get into 5th. But it slips if I give it any more than 10% throttle.
I can make it home maybe lol!
An adventure for sure
