: I have an automatic '73 I6 250 Mav and when I start her up cold she doesn't seem to want to slip into second gear. First gear revs so hard it sounds like she's going to blow and finally after a few blocks, it pops into second and about gives me whiplash. The same happens for third gear. I have checked the fluid and there is plenty in there. Does anyone out there know what this might be? Thanks for any input.
Have you tried manual shifting. Might loosen anything that might be sticking. Changing the fluid and filter will probably help, and maybe even getting it adjusted by a professional. If it's shifting fine, just might need some adjusting, or a modulator. Check the vacuum lines to the modulator. There may be a small hole in the rubber line that swells after being heated. Good luck...
