Built Ford Tough.

The 4 speed toploader is one of the toughest manual transmissions ever built.

Identification of the Toploader is easy. Toploaders are top accessible (from a 10 bolt steel plate)

The transmission serial number is a production serial number and should not be confounded with the engine serial number, they are not the same. Some transmissions have a date code instead of the serial number. 2 different INPUT shaft are commonly available for all V8 Ford's, 1 1/16' and 1 3/8'.

For decoding the specific application look for a metal tab riveted on the right side of the transmission body housing.

HEH-? or RUG-? are the codes necessary for decoding specific transmission application from the

Decoding the Toploader

For most 60's and 70's Toploaders the ID starts with either prefix HEH or RUG

The lower number on the tag is the transmission serial number. The transmission serial number is a production serial number and should not be confounded with the engine serial number, they are not the same. Some transmissions have a date code instead of the serial number.

Input Shaft

2 different INPUT shaft are commonly available for all V8 Ford's, 1 1/16' and 1 3/8'. But both input shafts have the same number of splines of 10.

Bolt patterns (bellhousing)

2 different bolt patterns. Early Toploaders used a narrow bolt pattern type for attaching the transmission to the bellhousing and the later versions used a wider butterfly type bolt pattern.
