Kate, this doesn't work well on the GT version of the T-45. See my reply to Mike.

*exactly* 5mph off at speeds lower than 60mph... dunno a/b above b/c I didn't take her that high yet (and won't until after 100 miles). I can "smell" the gears breaking in I think. Could be just me. *shrug*. 3.73 gears w/ new bearings installed... used havoline 80w90 gear lube to break the gears/bearings in. The gears are worth every penny already & I haven't even stepped on it. Reverse is FAST.. caught me off guard. Almost reversed into traffic from Pro Speed. I can get great gas mileage now too... I can actually cruise @ 1300-1400rpm in 5th going 45-50mph.-Mike
I went to dealer (didn't read this first) & they didn't even have one. Just
2.73 & 3.27 speedo gears.-Mike
I might be, and I am more then likely mistaken, but can't you change the gear ratio in the computer using a higher end scan tool??
I wan to say 98 was the first year for that, but I can be mistaken.

Oh man! really! Tom, they don't put the same tranny in the cars? I could have totally fugged him up if you hadn't stepped in.

Nope, not 'til 1999 models.

It's the same tranny with different external mounting points and a different internal drive gear. The Cobra version utilizes a 7-tooth internal gear while the GT version uses an 8-tooth.

I'm going to go buy Mobil 1 75w90 gear oil today. I plan on driving it easy for another 200 miles today & getting the good stuff in the rear-end & stomping all over it today. I can't wait!!

Mike, you are a bad influence. I'm sitting here with debit card in hand playing the shall I or shall I not order some gears game :-) wanna bet which wins?
Dave
LOL. I'm telling you... they are worth every f*cking dime. FRPP 3.73 gears ordered directly from
I cruise around in the city at 1400RPM in 5th gear & am getting *killer* gas mileage. It's been over 350 miles & I'm still on that same tank that I put in before I got the gears. I'm sure I can make it to the 450~480 miles range on this tank alone. I've got plenty of gas left.
IMO, and without even had stepped on it at all... they're worth it. I didn't expect a whole lotta oomf.. but wow. It's no supercharger or anything... but it is the best bang for buck. You'll hear more testimonials after I step on it LOL.
-Mike
Oh also... I know MustangTuning.com says Motive gears are just as good as FRPP gears, but cheaper... and so far I've heard nothing but the same from all of the local performance shops. A friend of mine (Stan) in his 95 GT runs Motive 3.73 gears & they've given him trouble-free performance for 105k miles now. I thought he had FRPP gears which is why I paid a little extra for 'em.. but Motive is apparently just as good.

I got 498 miles on the tank... *most* below 60mph actually. Speedo is 5mph off below 65mph... so I got somewhere close to 30mpg on that tank. Drove like a granny the entire time... but I got the mileage. More than I ever thought this car would give me. It's time to change the gear oil...
-Mike
lmfao
Mike, I hate to bust your bubble here but your mileage probably isn't nearly as good as you think it is. You have to realize that your odometer is also screwed up as is your speedo. Here's a way to figure your actual speed in 3rd, 4th, and 5th gears:
In 3rd at 2000 rpm your speed is 31 mph In 4th at 2000 rpm your speed is 42 mph In 5th at 2000 rpm your speed is 62 mph
Having done the same gear swap in my car and seen data from countless other people who have the same setup my guess is that you'll see about
25-26 hwy and 22-23 mixed. My city mileage actually went up a little because the 3.73 gears put the motor in a much better operating range than the stock 2.73's.If you want to do some more calculations, go here:

I know it's a fairly big improvement. Have you heard anything about hypertech programmer for our cars? I was thinking about buying one for the speedo correction, but was also hoping to get a bit of a HP gain if it actually did offer anything. Checking out that URL..
