Ok here's the question... I have a 94 Chevy pu with a 4L60 overdrive trans in it (Ithink). Why don't they want you to tow in overdrive??? Seens to me that if the verter is locked why would it burn up the trans?? Is there to much load on overdrive?? Can it be "worked" to tow in overdrive??? :-k Barry

Had the same thing with my motorhome, it keeps wanting to shift down up down up on any slight hill.

The way I understand it that is the problem. With a heavy load the engine doesn't have enough torque to pull the load in overdrive, the engine boggs and the trans. shifts down, then when the rpm levels off it wants to shift to overdrive so it's constantly shifting up and down putting an excessive amount of wear on the clutches/bands that are used for this shift. All the wear occurs in an automatic trans. when the clutch or band is being applied. By turning off overdrive you stop the constant up/down shift thus reducing wear and tear.

So if the trans is in drive will the converter still go into lockup??

Or how about making a switch to manually locking overdrive in when on the highway so it don't go in and out. Am I thinking to much??? Try to save gas =; =; =; Barry
