How often should I change trans (5speed) and rear diff oil ???

And what oil is good ???

 

I cannot remember recommended mileage on manual fluid change but I do mine at around 15-20K miles. Last time I switched to Redline MTL and found the tranny runs quieter and shifts a bit better. Worth a try.

Typically it is around 50,000 - 60,000. Fuel filter is around that interval too. If you do it yourself, You could do it more often like scott, that won't hurt. but it can sometimes be costly, and waiting until 50k, won't hurt it at all. I will be doing mine in the next couple of weeks, I am at 65k, I am switching to synthetic.
