What different transmissions came in 85 (or actually any S truck with a 60° V6 (so it'll bolt up to my 2.8).) trucks? How do I identify these. I have a 5 speed. I'm having trouble with my second gear synchro (the da#n thing keeps jumping out of gear (started a while ago, for no apparent reason...)... Does anyone know of a stronger transmission to bolt directly in place of this 5 speed? Or would a fresh 5 speed work alright? /wwwthreads_images/icons/crazy.gif
Another related question: What kind of fluid should I use in this 5 speed? I think the Haynes manual says ATF, but I was wondering if anyone has had better luck with some other type of lube (10W30, 15W50, gear lube or anything else you've had good luck with) I'd probably be using synthetic lube in there when I do change it... /wwwthreads_images/icons/crazy.gif
