The 55 Pontiacs used the smaller Buick built 3 speeds. These trannys were built originally for use behind flathead sixes and eights of 100 HP or less. All 35 to 55 Pontiac, 35 to 48 Olds and 36 to 55 "junior " (series 40 & 50) Buick trans should bolt up to the 55 Pontiac bellhousing.
If all your doing is normal street driving, then this transmission would be OK. I would certainly not recommend "Hot Rodding" it or trying to put more than 250 HP through it.
