Benefits of the GM Powerglide
Over the years many types of transmissions have been utilized in medium to high horsepower bracket and class-style race cars. Although there are numerous transmissions available for racers to choose from, the GM two and three speed automatics seem to be some of the most popular transmissions in the performance transmission market. Many racers would argue that a Chevrolet Powerglide transmission, when matched with the proper rear gear, is the quickest and most consistent of all existing transmission designs.

Easily Add a Powerglide to your HEMI
This is great if you own a vehicle with a GM engine, but what if you have a HEMI 5.7L or 6.1L? This ATI adapter kit allows Chrysler owners to benefit from the GM transmissions as well. Before the ATI adapter kit, many hours of expensive fabrication were necessary to mate GM transmissions with non-GM HEMI engines. With the introduction of the ATI adapter kit you now can perform the operation in less time with less fabrication required. The ATI adapter kit includes an ATI adapter plate, an ATI crank adapter, an ATI Flexplate, and all the necessary mounting hardware to correspond with you Chrysler engine. The only fabrication that is required is cutting the plate, so that it matches the profile of your bell housing. This is accomplished by mating the plate to the transmission and tracing the outline with a sharpie. Then, have the plate cut along the line you traced. This kit also requires a new starter from Mopar Part#05030023AA

ATI Quality
The ATI adapter plate is made from 0.5" thick 6061 T-6 heat-treated aluminum. The plate measures 20 inches high and 24 inches wide and may be incorporated into an engine mid-plate. The ATI crank adapter is fabricated from heat-treated steel and bolts to the crank to ensure exact converter and flexplate location. This adapter also accepts the OEM diameter and length GM converter pilot. Each crank adapter is designed utilizing OEM drawings and dimensions and produced on ATI's state-of-the-art CNC turning centers.

SFI HEMI Flexplate Included
The ATI Flexplate is created from custom drawn SFI-spec chromoloy steel. This unit is double MIG/TIG welded for additional strength and lasting precision pass after pass. Each ATI flexplate is manufactured and toleranced from actual OEM drawings to ensure a precise fit and location. Each plate is quality inspected to EXCEED the flatness and run-out tolerances of the OEM units and is precision balanced on Hines digital equipment with a resolution of 1/10 ounce/inch.
