The car I keep around for my teenage kid's is getting a bit long of tooth (1993 Jeep Grand Cherokee 300,000 miles).

A friend has a 2000 Jeep Grand Cherokee (4.7 V8 4X4 Auto Trans 150,000 miles) she wants to sell ... since the transmission puked about 6 weeks ago. She bought a new 2011 Jeep Grand Cherokee and parked the old one on the curb.

I plan to offer her Kelly Blue Price less the cost to replace the transmission.

What is a guestimate of the cost to replace the transmission?

I plan on making my teenage kids help me install a rebuilt or used transmission ... or walk to school ... their choice.

Thanks,

Eddie
