Here at PerformaBuilt our goal is to engineer and build the toughest transmissions on the planet. We don’t just rebuild transmissions. We systematically re-engineer each model to eliminate OEM flaws and to achieve the highest levels of performance.

Our hallmarks are quality, performance and unparalleled customer service.

The latter is what sets us apart from our competition and has allowed us to grow at a phenomenal pace. We are there before, during and after the sale to support our customers. All transmissions are dyno tested before shipment.

Here are nine great reasons why you should buy a PerformaBuilt transmission or converter!

1. We build the best transmissions and converters in the world!!


2. The best warranty in the business. 1 year for the transmission alone, or 2 years if you buy a transmission and converter package.


3. Race them all you want! Racing a PB transmission does not void the warranty.


4. Outstanding customer service. Seven days a week by phone, e-mail, or IM. Thorough installation instructions with every purchase. We support you before and after the sale!


5. Our $950 RESTORE guarantee. Any time after the warranty expires, send us your transmission and we will restore it for $950 (including all parts, labor and shipping "mainland US only") and give you a new warranty.


6. Proprietary packaging allows us to ship all of our units UPS Ground (except 4L80E). No more truck shipping!!


7. Free shipping for all transmissions within the continental United States.


8. Free external cooler and flush kit with every transmission purchase.


9. No core charges or core required.

PerformaBuilt level 2 4L60E - Awesome.

Picked mine up for 1600 with free shipping, a year warranty, and a cooler. Got here in 3 days. Rated for 700 whp and let me tell you, it's perfect. Shifts at WOT are nice and solid, while daily driving it feels just like a stock one. Can't feel it shift at all. Everyone who i talked to at PerformaBuilt were all great to work with.

If you're looking for a great tranny for hardcore performance and good DD'ing, i would reccomend PM'ing PerformaBuilt or visiting their website to see all their trannys.
