Good job on jake-shifting the old girl. Had that happen in the semi one time, coming down Crowsnest Pass in AB, at 80K lbs, and a delivery east of Calgary. Made it to the customer on no clutch, including crossing Hwy 1.
Just to give you a frame of reference, my 96 F250 is at 360K, and on her second clutch. You're a little ahead of the curve....
