1948-55 Dynaflow Lip Seal Kit, 3 pieces. Includes the Clutch Piston Lip Seal and Reverse Piston Lip Seal which are made with the latest polyacrylic lip seal material. The low servo piston lip seal included is the original nitrile material as they were never made in polyacrylic. I also sell overhaul and rebuilding kits for all 1948-63 Buick Dynaflows plus many other misc parts, please inquire. Note: See my item number 134351247722 if you want to order more than one or if you are being shipped to outside the US.

I ship this free via USPS 1st Class 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. They come with insurance and full US free tracking and you will receive this tracking number which you can then track your order if needed. If USPS shows your package is not delivered you will receive a full refund. I will also ship anywhere in the World via the US Postal Service except India. I will only ship to India via UPS or FedEx due to extreme problems with shipping via USPS.

The cut off date for Monday through Saturday shipping is 9:30 AM Eastern time and I will try to ship any orders that is received by this time if possible. I personally operate by myself 7 days a week, 52 weeks a year and ship 6 days a week. 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 have been selling new automatic transmission parts exclusively for vintage cars, 1946 to the mid 60's for over 45 years now, starting in 1977.  During this time I have accumulated over 30 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.
