Eight-speed transmission repairs

by David Zatz on

When Allpar posted allowable nine-speed transmission repairs, the question arose: what about the eight-speeds?

Due to the precision required for both ZF or ZF-based automatic transmissions, dealers are not allowed to rebuild the transmissions in many cases. However, dealers can replace the following items without pre-authorization:

  • Oil pan, filter, and gasket
  • Seals: gearshift shaft, output shaft, manual lever shaft lip
  • Replacement of the valve body, torque converter, output, parking pawl and rod lock

The company told dealers that oil pump replacements are not allowed, and that they must return all parts and a diagnostic worksheet.

David Zatz founded Allpar in 1998 (based on a site he had begun in 1993-94), after years of writing reviews for retail trades. He has been quoted by the New York Times, the Daily Telegraph, the Detroit News, and USA Today. Before making Allpar a full-time career, he was a consultant in organizational psychology.
