2006 Sightseer 29R transmission

As has been stated to know for sure get a pic of the shift lever. If it has the T/H button it’s the 5 speed if it’s got the O/D button it’s the 4 speed. Either one is capable of hauling around the weight it rated for. The V-10 4 speed combo really shines with a custom tune from 5 star tuning.

Ford extended the production of its 2004 model F-53 chassis with a 310hp V10 and "Ovedrive" button on the shift lever (4 speed) till December 31st of 2004. On January 1, 2005 they began production of the 2006 F53 with the newer 362hp V10 and the "Tow-Haul" button on the shift lever (5 speed). It was a huge upgrade for the chassis. The 2006 chassis is much preferred but the older F53 isn't bad either. It's just that the extra gear and horsepower really make a difference I'm told.

The 10th digit of the VIN would indicate the year of the chassis.

Is more than an extra gear. The tranny controller keeps the RPM higher in all gears and allows engine breaking. This put a lot less stress in the transmission. I have had motorhomes with over 300K miles with that transmission with no problems.

Get the VIN, then run the number for a build sheet.
