Your transmission tune, back in your inbox within one business hour.
Read your truck with your HP Tuners interface, upload the file, tell us what you want changed. We calibrate the shift tables and the converter the way we set up the units we rebuild, and send the file back the same hour.

What actually gets changed
Every file is edited by hand against your request. These are the tables we work in and what each one does for you.
Shift firmness and timing
Shorter target shift times and more clutch pressure on upshifts so the shift is crisp instead of smeared. Coast shifts stay soft.
Shift points
Part-throttle lines moved so it holds a gear instead of hunting, and spaced so one shift doesn't trip the next.
Converter lockup
Factory slip control replaced with a firm on/off apply at full pressure, with lock and release speeds set per gear. This is the usual fix for shudder.
Skip-shift behavior
Where the factory skips 3rd or 5th at light throttle we re-space the schedule so it walks through the gears.
Tow/Haul and limits
Earlier lockup and longer gear holds under load. Speed limiter, rev limiter, tire size and gear ratio corrections with the driveability package.
What we leave alone
Emissions equipment and its diagnostics, fuel and spark on a stock engine, and anything that trades durability for feel. If a request would hurt the transmission, we'll say so before we touch it.
Platforms
One price per platform. If yours isn't listed, write in on the order form and we'll tell you whether we can take it.

"Send-in" and "Direct OBDII upgrade" are HP Tuners' one-time module upgrades, done before the first tune. What your truck needs walks through every one.
How it works
Read the truck
Check what your truck needs — most need nothing, a few newer ones need a one-time module upgrade first. Then plug in your MPVI, read the vehicle in VCM Suite and save the .hpt file. Your interface, your license.
Start an order
Pick your platform and package, upload the file, and tell us what you want changed in plain language. Pay on Stripe's secure page.
We tune it
Your file goes to a tuner who rebuilds these transmissions for a living. Within one business hour you get the tuned file and a written list of exactly what changed.
Flash it, drive it
Write the file with your MPVI, reset the transmission adapts, drive it. If anything needs adjusting, send a log — one revision is included.

Questions
Do I need my own HP Tuners interface?
Yes. An MPVI2, MPVI2+, MPVI3 or MPVI4 with your vehicle licensed on it — a few newer trucks need an MPVI3 or MPVI4, and GM Global B vehicles need an MPVI4. We only ever touch the file; the reading, the license credits and the write are all yours, which is also why you never have to ship anything or leave the truck anywhere.
Does my truck need an unlock first?
Some do. HP Tuners requires a one-time module upgrade on certain newer controllers before they'll take a tune: a send-in service for 2015+ Ram/Dodge gas PCMs, 2022–2024 Ram Cummins ECMs and GM Global B transmissions, or a Direct OBDII upgrade you do yourself for GM T93 transmissions on Global A vehicles. Most GM 2017–2019 trucks and every Ford on our list need nothing. The order form checks your platform and model year and tells you before you pay; the full list is on the what-your-truck-needs page.
Can you do the unlock for me?
The module has to physically go to HP Tuners, so the shipping is on your end — but we'll send you removal and relearn notes for your truck. For 2022–2024 Ram Cummins there's a no-shipping option through an authorized HP Tuners reseller; email us and we'll point you to one.
If I only want the transmission tuned, do I still need the engine unlock?
Depends on where the transmission tables live. On Ram Cummins (2010+) and Ram Hemi HD trucks the transmission is controlled inside the engine ECM or PCM, so yes — the ECM/PCM upgrade is required even for transmission-only work. On GM 8/9/10-speeds, Allisons and every Ford on the list the transmission has its own module that licenses separately, so no engine-side service is needed.
Does my interface need to be plugged in while you tune?
No. Tuning is file-based: you read the truck, send us the .hpt, we edit it, you write it. Your interface is only needed at the truck — to read, to license, to write, and to run any Direct OBDII upgrade the first time.
How fast is one business hour, really?
Orders placed between 8 am and 6 pm Central, Monday through Saturday, are delivered within 60 minutes of payment. Anything after hours is first in the queue the next morning. Your order page shows the promised time the moment you pay.
Will it throw codes or hurt my warranty?
The tables we change don't set codes on a healthy transmission. Any calibration change can affect your factory warranty, and a dealer can see that a vehicle has been tuned — we don't hide that from you. Keep your stock file; we send it back to you with every order.
Is this an emissions thing?
No. We work in transmission and driveability tables only. We don't modify or disable emissions equipment or its diagnostics, on gas or diesel, and we won't take orders asking us to.
What if I don't like how it drives?
Tell us what you feel and send a log. One revision is included for 30 days and we keep revising until it's right. Delivered files aren't refundable — they're digital goods — so the guarantee is the revision, not the refund.
What's in a log and how do I take one?
VCM Scanner, channel list we send you with the file: gear, commanded gear, TCC slip, trans temp, throttle, engine torque, and shift time. A 15-minute drive with a few full-throttle pulls is plenty.
I have a built transmission or an aftermarket converter.
Good — say so on the order form with the stall speed and what's been done. Converter stall and clutch pack changes change what the right numbers are.
What happens to my file?
It's stored for 90 days so we can do revisions, then deleted. It's never shared, sold or reused for anyone else's vehicle.
