Just picked up a new transmission for my single cab f150 and the new
transmission is about an inch longer from the rear seal to the end of the
driveline. will this matter when i put it in. other than that the two look identical.
Yes, it could cause the driveline to bottom out on the slip yoke, the yoke slips in and out on the output shaft in the tranny as you drive and or carry any loads, if it bottoms out it can destroy your transmission by shoving the output shaft froward through the case.
