Re: 92 4runner shifts really hard between gears
I'm not sure my reply will be of any help, but I have had a simliar
problem. I have 94 p/u with an auto and a 4-banger and shifted exactly
as your described it. I would start with looking at the vacuum hoses,
vacuum switch valve (vsv), and checking the throttle cables. When I put
back together my engine, some of the hoses were off or were cracked. I
replaced all my vacuum hoses, and cleaned out this filter thing. I
can't remember the name of it, but I'll post when I remember it. For my
truck, adjusting the throttle cable seem to do the trick, it's still a
little rough, but I think I can adjust it some more to get what I want.
Also check the throttle position sensor as described in the
haynes/chilton manuals. Hope that helps you to get started.
