Torque Ball Retainer Kits for 1948 to 1960 Buick's with the Dynaflow transmission. You must specify the year as there are 4 different kits. They are 1948-52, 1953-55, 1957-58 and 1959-60. Check out the pictures to see what each kit includes. All of the kits include the TB retainer with the rubber bonded inside as pictured plus the correct o'rings, gaskets and rear seal for your year. The original 1948-55 shim kits are no longer used with this new style retainer.
Note: See my item number 134281916593 if you want to order more than one or if you are being shipped to outside the US.
Note: Regarding the 1956 Dynaflows - It uses the 1953-55 kit but some 1956 torque balls (AT-5645) had rubber molded on the inside also. Do not remove the rubber on the inside unless it has been damaged! If you have to remove the inside rubber, or it has already been removed, you will now require a different style of AT-5643, the inner torque ball retainer, to get the clearances correct. I do not have this special retainer.

I ship this item free via Priority Mail to any location that has a US zip code, this includes Alaska, Hawaii, Puerto Rico, the Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands and also any APO or FPO address. It comes with full US free tracking and you will receive this tracking number which you can then track your order with if needed. If USPS shows your package is not delivered in a reasonable time you will receive a full refund. I also ship anywhere in the World via the US Postal Service, 1st Class or Priority Mail, except India. I will only ship to India via FedEx or UPS due to extreme problems with shipping via USPS.

The cut off date for Monday through Saturday same day shipping is 9:30 AM, Eastern Time. I personally operate by myself 7 days a week, 52 weeks a year and ship 6 days a week Monday through Saturday. Since USPS ships and moves product 7 days a week, the majority of domestic customers will receive their order via 1st Class Mail in 3-4 days and via Priority Mail in 2-3 days, rarely 5-7 days after PayPal payment, no matter what day it was paid for. I can ship UPS also if required but shipping can then take up to 5/6 days if you are on the West Coast.

I have been selling new automatic transmission parts exclusively for vintage cars, 1946 to the mid 60's since 1977.  During this time I have accumulated over 20 tons of misc. mechanical car parts from the early 30's to the 70's. I am now starting to offer these parts for sale, check my listings.
