The gear ratio of this S-197 spec T-5 is 3751 first with a 73 overdrive. The 85-89 internal gear set options are as followed- 1st- 335 2nd-193 3rd-129 4th 100 and 5th-68.

Mustang t5 gear ratios. T5 Mustang Transmission Specs and Details. Out of all the Mustangs manual transmissions few have seen nearly as long a life as the T-5. Through three generations of Mustang the T-5 remained although it saw several upgrades through the years and there are several different sets of gear ratios depending on your Mustang.
I think the lowest Id go in terms of a rear gear ratio with a T5 would be a 350 or even slightly higher with a 373. The only issue with a numerically higher rear gear is that first gear is going to be reduced since you have a 335 first gear as opposed to the 295. 1985 then introduced the newer World-Class T5.
This transmission still had the same overall power rating of 265 lbft but upgraded internal gearing made this a better application for the upcoming changes over to electronic fuel injection. The 85-89 internal gear set options are as followed- 1st- 335 2nd-193 3rd-129 4th 100 and 5th-68. First gear is virtually useless since the overall ratio is 1249.
This is why a 295 First-gear T5 or the Tremec 600 287 trans is far more desirable if your plans include deep rear gears. Given a standard T5 has a 5th gear ratio of 68 and the T5z is 63 if I were to switch both transmission and rear end to the OPs setup I would have to go 50mph to maintain 1500 rpm. 67 mph would be 2000- rpm.
The gear ratio of this S-197 spec T-5 is 3751 first with a 73 overdrive. While this is great in getting the 40L Mustang rolling down the road it doesnt have a lot of strength or performance. Many owners of the 40L Mustang upgrade the clutch only to find the T5 with broken gears or wishing for a closer ratio gear set.
To pick a gear you need to know what ratio you currently have and where you want to be. As mentioned above Mustangs came with anything from a 2731 to 3731 ratio. If you are unsure of your ratio you can call the dealer with the VIN check the glovebox for production codes or look at the differential itself there should be a small tag attached to it.
The number of times the driveshaft rotates for each rear wheel rotation is your Mustangs rear gear ratio. This is also sometimes referred to as the final-drive ratio since its the last gear that must turn before power hits the pavement. If you have a rear gear ratio of 331 the driveshaft rotates 331 times for each wheel rotation.
The T5 is a 5 speed transmission that came in a very large variety of gearset options. One of the common gear ratio selections in the high power option is 295 in 1st 194 in 2nd 134 in 3rd 1 in 4th and 063 in 5th. The reverse gear was given a ratio of 276 in this application.
Materials Size and Weight. While the four-cylinder T-5 may appear to be the same externally as the V-6 and V-8 versions they are not the same box. Most four-cylinder T-5 transmissions received a 3971 gear set with a 079.
The black 6 tooth internal drive gear was originally used in the 4 speed tranny but works great to exactly correct for 410s when used with a pink 19 tooth driven gear. 83-89 T5 has a yellow 7 tooth internal drive gear. 90-95 T5 has a greenishyellow 8 tooth internal drive gear.
In 1990 the Mustang received another world-class T-5 upgrade to enhance further the already stout capability that enthusiasts came to know. Designed with a more robust 335 gear set each was built with more substantial nickel content for a much more reliable gear. The easiest and surest way to identify the original application or gear ratios of a specific used Borg-Warner T5 transmission is to check and look-up the ID tag number using the chart below.
Youll notice that the chart contains a few abbreviations. Most owners tend to choose a 355 373 or 390 for a Mustang that is daily driven. If you are serious about speed then you might consider the 410 or a 430.
Auto car or Stick. 327s are usually the gear of choice for optimum performance. The whole idea is to put a good load on the motor to spin the turbo good at low RPM.
Sep 28 2009 3. The T-5 five-speed transmission was developed for a broad range of vehicle applications from passenger car to compact sport utility vehicle SUV requirements. The TREMEC T-5 has been used on various passenger car and light truck applications.
Its largest application was the Mustang GT. In the 1990 the World Class T5 used in Fords was upgraded with stronger 335 gear set with higher nickel content to create a stronger more reliable gear. The 2nd and 4rd gear ratios decreased a little too.
The synchro linings on the 3rd-4th gears were improved with carbon fiber for better shifting ability.
