Ok I know all the Fiero 4spd ratios.
3.32
3.65 and
4.10
But our trannys were used in many other cars and they had diffrent ratio's. I am trying to find out what they had. I am getting sick and tired of guessing what trans is in my car.
I just (yesterday) installed yet another tranny into my car. The one I installed last Saturday, blew up this Friday. The tranny shop says it is probably a 30cent clip that let go inside the tranny, but none the less, it had to come out becuase I no longer had any select movment.
Now back to the current question
My current tranny speeds are as follows.
2nd gear 6000rpm is 63mph
4th gear 60mph is 2000rpms
4th gear 87mph is 3000-3100rpms.
I am guessing that this is the 3.32 ratio or something close to it. We ran my car on a GPS to verify speedo and we used a timming light hooked to the tach to verify my tach readings. (tach is constant 10% over so all numbers are corrected for that)
So does anyone have any info on what other ratios came in the Muncie 4spd's
