Re: Parts for Turbo 400 Install
Have a M40 in my Z24 Impala. Speedometer always has been low 8-9 mph. I did an transmission OH years ago when i did the body off. My techs; many in my chevy dealership have been with me 30 years, are telling me it's a plastic gear in the case causing the trouble. I remember different colors/teeth and I need help in identifying and replacing it. Any help out there?
