HELP ME OUT PLEASE
 

I have a 1994 Mustang GT which i recently put 3.73 gears into. i knew my speedometer would be off after i did this. it is now currently off by ten miles an hour. how do i fix this?

get a tuner with the right tune and you should be good to go.

here is what you need and much cheaper than a tuner just figure out which one you need based on the trans and year;)

/\/\/\/good post i for got about thouse.

that's cause your car is to new lol :D

awwww thats sucks, but hey a tuner is better, lol

but it costs 20X as much:eek:

just replace the speedo gear in the tranny. Takes about 20 minutes and plugs into the side near the tailshaft.

after looking at this thread and that oil thread it looks like 3.8Lmustang really likes to pay out the ass.

lets keep this thread on track.

Thank you very much for all your input.

Do they make tuners for cars without the OBD II? since mine is a 94'?

the SCT stuff works on your car. I know for a fact it does.

What R3D said, I think it's a 21 tooth speedo gear for 3:73.. maybe referred to as "white"?

Edit.. 21 tooth is "red" .. whoops
