A lil searching this morning ..........

The P-type overdrive marked the last updates and included both a Gear Vendors U.S. version and a Volvo version. The Volvo version kept the same package size as the J-type but with the updated 18 element freewheel and stronger splines through the planet carrier. The Gear Vendors U.S. version uses a larger 1.375 od output shaft for higher capacity and a longer rear case.

Over a period of 40 years, Laycock Engineering manufactured over three and a half million overdrive Units, and over one million of these were fitted to Volvo motorcars.

Also from the Gear Vendors site .......
In order to be the Best we had to have the best product. The product design is ultimately the most important aspect and it is known worldwide as one of the best designed transmissions ever. GEAR VENDORS did not invent overdrive or the original patents on our product. DeNormanville (maybe the most famous transmission designer ever) created the original product which, GKN (a 6 billion dollar/year public automotive conglomerate) acquired to produce this product for Ford and Volvo. GEAR VENDORS is a licensed manufacturer for GKN and in 1979 started applying racing expertise to the original design. The highest honors in the industry were won by GEAR VENDORS in 1981 with SEMA's Best Engineered award and again in 1989 (this unprecedented 2nd award for the Ptype configuration is the only time SEMA has given the engineering award twice on the same product by a manufacturer). No competing product has even one such award.
