I have a 1978 Chevy pickup and it stopped shifting. I called several shops trying to find out what it could be. I really got nothing... Most of them just wanted to have me bring the truck to them and they wouldn't give me any information or prices over the phone. Alas! I called Modesto Transmission spoke with Eric and he told me not to worry it may be something minor. He asked me several questions about what my truck was doing and diagnosed it over the phone. I towed my truck to them and I was surprised how clean there shop is.
