got the 1990 few weeks ago, couple issues..

power wise, it s a dog......but may be related to tranny problems.

the tranny shifts real hard from 1st to 2nd, then a very delayed shift to 3rd

i guess i m going to be doing a tranny..

97 k on odo...... thanks

Those sound very similar to my original issues. I would be checking a few items before getting a trans done.
1. vacuum modulator and line to modulator
2. new fluid and filter
3. bowden cable
vacuum is first and most in my eyes.

had some time tonite to get under the hood a bit........found all but one vacuum connection off the .egr. found the kickdown switch out of it s holder, button works, and snapped that back in..

found what i think is the tranny modulator, looks all intact. on the drivers side of tranny..

and cleaned / lubed up all the linkage.........thats alot smoother now also.....

ok, another find ? , what s the little box, next to main fuse box drivers side under the hood. looks like a 4 pin relay / fuse thingee ... top is broken off and looks like fuses used to be inside...

many thanks ! !
