that's what i'm getting at.  i've driven a lot of cars with 3.73's and they didn't feel so short.  that's what makes me wonder if the tranny isn't a v8 tranny.

A V8 tranny won't cause the problem, they have either 3.35 or 2.95 1st gears...  The four banger tranny has a 3.97 1st cog...


Factory the '87-'88 5 speeds have 3.55s and the auto's 3.73...


Guessing you're suffering from "AWOIS" (All Wound Out IHI Syndrome)... After 5K ain't much happning'...

could be the opposite problem. my early tranny has a 4.03 first gear. with 3.45's in both my rangers 1st and 2nd both felt too short.

i am gonna try a set of 3.27's this time around and see how they work.

the ranger still has the m5od with the factory 3.45's and it's  near perfect.

True, but I have doubts about being able to feel .06 difference in ratio...

So whats the 1st gear ratio of the M5OD???

so, if youve got 3.73's, was the car originally an auto? if so, i would bet that youve got an tranny with a 4.03 first based on the cable clutch setup.

.06, multiplied by the .28 difference in rear gear that he is accustomed to, could be felt for sure


im sure its jus "different." jus gotta figure out exactly what you are workin with to know what to change

OK you're likely correct, I wasn't considering the difference in rear ratios...

yup, 3.72 should be correct for his ranger.

i didnt recall the M5OD ratios, but that puts an even larger gap between what is in the ranger and what is in the TC
3.72 and 3.45 vs. 3.97(or 4.03) and 3.73

sounds like its time to figure out what tranny is in there for sure, and pick a new rear gear if you dont like the 3.73's

I believe the site I plucked the info from lumps all the RWD trannys into one category... Why they are calling the T5 a M5 I dunno...

Looks like I left off the T5...

At any rate the WC T5 4cyl tranny has a 3.97 first gear... the '84 non-WC tranny was 4.03...
