So I installed a new tranny filter on my 90 jimmy. /forums/images/graemlins/1zhelp.gif. Filled it with new fluid. Changed my cap and rotor and added a throttle body spacer. Now everytime I put it in drive it hits hard (like it does when in 4lo) also the whole truck shakes at idle. Now with my old blazer when it was shaking it meant the idle was to low so i turned up the idle and it ran perfect. Well if i turn up the idle on the jimmy it will be at a higher rom when I shift into drive and therefore will hit even harder right? I am confused. Did I mess something up. Could the shifting hard be because of the tranny cable coming onto the tbi. If so how do I adjust this? Any help please?
