Overdrive Transmission Question

a GV unit isn't 3500 I paid 2800 for mine a few months ago. but I picked it up no shipping cost

Ok. It's been a year or longer since I looked. Still $2800 is a bunch of money. Figure extra's like fluid and getting the driveshaft shortened and your over $3000. My point was you'd have to do a bunch of driving to save $3000 on fuel. Don't get me wrong, I'm not knocking it at all cause it's a great product and makes the car drive much better I'm sure. Just saying it's not cheap at all and it'd be hard to save anything going to it unless you drive a lot and plan on keeping the car for several yrs.
