DX and SI transmission, the difference is the gear ratio thats it....
I remember looking at the gear ratio on a website
DX tranny was 3.87
SI tranny was 4.37
FINAL GEAR!!!
as for 1st-4th same ratio's, 5th for an DX is a little lower than an SI, this is all i remember....
Taking out a transmission is SIMPLE, like people say, if your good its done in 1 day....Just got mine done a week ago...out of a crowded 91 CRX runs perfect..
My way of doing things...quick walk through....
Took 2 jacks with 2 jack stands....place a hard woodboard or something familiar just to fit for the OIL PAN to sit on with some cushions...Hit out the pin for the linkage, place the other jack under the transmission, jack up just enough so it lifts it off the mounts so there wouldnt be so much pressure taking off the bolts....take out starter before you start on mounts...take out speedometer cable which HAS A CLIP on the tranny THAT HOLDS IT..(I ruined my speedo by trying to yank it out knowing the clip holds it in place) Clutch cable comes off easy by just un-screwing the holder and slide it off the tranny fork....Unbolt the 5 bolts that holds the tranny, pry it with a thin fat flat head slowly all the way around the tranny....There is 2 dowel pin that holds the transmission also, slip the tranny off until those 2 pins are clear then lower it down with jack careful not to damage the pressure plate with the main shaft..(ANOTHER PERSON HAS TO HOLD THE TRANNY AND SLOWLY LOWER THE TRANNY)
NOTE: DONT RUSH THINGS....youll end up with more problems...
Took me 2 days, first timer under the hood of an CRX!! CROWDED LITTLE BASTARD...^_^ GOODLUCK!!!
