TREMEC Toolbox
The TREMEC Toolbox contains:
• Driveline Angle Finder: Take the guesswork out of your chassis setup with this handy 3-step tool! By using your smartphone as a measuring device, the app will calculate each u-joint angle and provide an overall driveline operating angle with a Pass/Fail response. Designed for RWD vehicles equipped with a one-piece driveshaft.
• Vehicle Speed Calculator: Interactively determine your vehicle’s speed in any gear and any engine RPM for best performance. You can alter the axle gear ratio, the transmission gear ratio and tire size to see the impact in real-time. As an added bonus, the calculator doubles as a Gear Ratio Calculator.
• RPM Calculator: Determine what RPM your engine will run based on gear ratio, tire size, transmission and MPH. Try various combinations to come up with the best combination of gear ratio and tire size for your vehicle.
• Tire Size Calculator: Convert the funky P-Metric tire size (Example: 265/75R16) on the side of your tires to inches to simplify these drivetrain calculators!

awsome app! provides the data I need to build a properly balanced drivetrain. no more guess work or listening to keyboard professionals. this program allows you to work with varying tire sizes and gear combos to find the perfect fit for your ride.
Awesone app to check speed vs rpm etc for different gearbox & diff ratio. The only thing it could improve on is if it had the option to have km/h not just mp/h. If it had that option i would give it a 5 star 👍
Driveline app doesn't work, angles constantly show zero. I've put this on two phones, and neither one works.
It's an ok app it takes some getting used to it I usually check pinion angle but this app does all 3 angles and adds them up and the green and red colors let you know what is off
App was great for a long time now it has a bug and I every time you type anything into engine rpm it crashes
Never worked for me just kept getting 00.0 readings app still needs work,great idea it just don't work
Used to work fine but now just crashes /closes as soon as I try using it. Very annoying.
Its telling me my 97 xj rear driveshaft is at 8 degrees stock height...... im not so sure that's accurate lol maybe I need to try again.
Worked fine for a long time now crashes like others mention
Don't work on my phone it work on my old one. Work very good in my old phone.
Love this app BUT it now will not work. Ever time u clik the app it closes. I have an android phone...is there a patch???
Simple, helpful, does not shut you down for advertising.
Fix the bug in speed calculation
Needs setting to change between metric and imperial.
Closes as soon as you open it to bad use to be a Good app
Not many apps outhere that can help you like thise. Best so far
Very easy to use
Great tool to have
This app doesn't respond,,it must be out dated
Will not pull up angle meater
Yeah it works.
I'm considering a final drive gear ratio change. The app does great calculating what I might expect in terms of engine speeds vs road speed in various combinations. My main complaint is that every time I change one parameter (speed, engine rpm, final drive ratios, etc), the app requires me to reenter all the transmission ratios. It's very time consuming and frustrating. Please set it up so that it remembers all entered data unless the user specifically requires the change.
One crucial part of this tool that needs to be added, is a calibrate feature. Not all phone's sensors are perfect, and some phones can't be calibrated, at least not mine. So all the angles were off by 1.5 degrees. I had to download another degree finder that has a feature to calibrate the phone's sensors.
Driveline angle finder reads angle for a second and freezes and won't read angle anymore, numbers just stay the same. Works on a friends S3. Real bummer I have other angle finding apps that work without glitching.
Doesn't work for driveline angles. I thought new technology would be better so I tried it against my angle finder. It was off significantly. The ultimate test was to put it on a bubble level. Should read zero on a bubble level, my angle finder does, this app doesn't. Was off by approx 8 degrees.
Drive angle won't go past first next button tried to reinstall and still does the same thing.
Saw off the latest episode of roadkill with 650hp red van and this app is a big time saver not to mention the mistakes saver
Pop up instructions disappear too quick, can't even read all the instructions.
Crashes all the time if you go directly into the Vehicle Speed Calculator. If you do a calculation in the other tabs 1st, it drastically reduces the chances of crashing. However, that shouldn't be necessary at all.
