What is the factory gear ratio in 92 mustang lx 5 speed?

The factory gear ratios for a 1992 Mustang LX 5-speed transmission (typically a T-5) vary slightly depending on the specific axle ratio used in that particular car. There wasn't a single universal ratio. You'll need to find the axle code (stamped on the axle housing usually near the differential cover) or look at the sticker on the door jamb to determine the axle ratio. The gear ratios will then vary *slightly* depending on that ratio choice.

However, a *general* representation of the T-5 ratios found in many 1992 Mustang LX 5-speeds is:

* 1st: 3.35:1

* 2nd: 1.93:1

* 3rd: 1.28:1

* 4th: 1.00:1

* 5th: 0.73:1

* Reverse: 3.38:1 (approximately)

To find the precise gear ratios for *your* specific car:

1. Check the door jamb sticker: This sticker often lists the axle ratio.

2. Locate the axle code: This will be stamped on the differential housing, usually near the differential cover. Use this code to look up the axle ratio in a Mustang parts catalog or online.

3. Once you know the axle ratio, you can search online for more precise T-5 gear ratios associated with that specific axle ratio for a 1992 Mustang LX. The variations are usually small.

Without knowing your car's axle code or the axle ratio from the door jamb sticker, the above ratios are the best general estimate available.
