I have a 94 Accord with auto trans. that really jerks hard when shifting
gears, especially from 1st to 2nd. Could this be due to worn motor
mounts? I ask because if you watch the motor when the other person
shifts out of Park into drive the motor seems to move quite a bit. When
looking at the front mount the rubber bushing seems to have a lot of
space inside it. Would this be a costly repair at the corner garage? I
have almost 200,000 on it.Thanks in advance for any info. Mike

More importantly, when was the tranny last drained and refilled? Has
anybody put non-Honda tranny fluid in it?

motor mount rubber fatigues and tears. when it's gone, it definitely
jerks and bangs about. but that's not the whole story. also affecting
shift quality, as curly says, is the correct transmission fluid - it has
to be honda to shift properly. then there's other stuff like the
quality and age of the oxygen sensor, and tension of the timing belt. i
found that an aging aftermarket sensor gives poor shift quality, and so
does a loose timing belt - it introduces a lot of flutter into the
engine rpm signal the ecu looks at when deciding to shift.

Crap, any correct a-t-f ( Dexron I / II / III ) will do : my F20A's
present gearbox* works fine with Argent a-t-f, only a lack of a
filter ( = a design flaw ) made its predecessor's lock up clutch jam.

If service schedule does not require changing a-t-f filter, then gear
box lacks a filter ( like Mitsubishi's ), so a-t-f cannot stay clean.

1 can [i] use a syringe & hose to suck ( via dipstick's hole ) a few cc
fr bottom of sump & see. [ii] fit a filter ( e.g. Mazda 323's petrol
filter ) onto the joint ( betw metal pipe & rubber hose ) of either 1
of ATF's cooling pipe. * was slightly noisy when in "neutral", until
its a-t-f was cleaned by the filter I fitted.
