well I got the old burban back from the shop today and the fellow had fixed the transfer case seal and parking pawl... I drove it to the center of town and then 15 miles home.... I thought it was driving a little funny... so when I was almost home, I parked it and look at the shifter... ....thats funny, looks like buddy at the transmission shop had put it in 4 LOCK !... so I shifted it into 4 hi and drove it the remainder of the way home.... the tires never broke loose around corners.... SO WHAT DID I DESTROY ON MY NP203? or could they survive a voyage on the pavement?
