Genuine Fleece Performance part.
The Fleece Performance TapShifter allows you to shift your 2001-2005 GM Allison Transmission with the touch of a button just like the 2006 and newer trucks. Perfect for towing, drag racing, daily driving and everything in-between, the TapShifter installs in no time and provides factory-like operation, functionality and styling. The TapShifter can be used in the gas or diesel 2001-2005 trucks with an Allison Transmission. Installation: The TapShifter installs using OEM high quality connectors for a completely plug and play installation in less than 30 minutes. Operation: TapShifter Operation is very straight forward. To downshift depress the "-" button on the shifter. To upshift press the "+" button. The TapShifter will allow you to select a range with the shift lever and then tap up and down without worry of tapping to a higher range than selected. This feature is great for sled pullers who do not want to shift to 4th gear on the track!

Manufacturer's Warranty — Fleece Performance

Manufacturer's Warranty — Fleece Performance
Fleece Performance Engineering publishes a Limited Warranty on new products for the US and Canada, and the term is set by product line rather than by one figure for the whole catalogue. PowerFlo lift pumps carry a Lifetime warranty — parts only, non-transferable, and it must be registered within 30 days of purchase at fleeceperformance.com or by the form packed with the product. Cheetah turbochargers carry 12 months, except the Cummins VGT Cheetah units (FPE-351-0712, FPE-351-1317, FPE-351-1920) which carry 24 months on units built on or after 19 November 2018 (serial 35-25744); earlier units stay on the original 12-month term. Cylinder heads carry 12 months. For anything not in that table Fleece directs you to the warranty length shown on that part's own listing. Coverage is parts only, runs to the original owner, and begins on the date of purchase by the final end user. A Return Authorization (RMA) number must be obtained from Fleece and the completed RMA returned with the product within 30 days, and all fuel-related products must be returned to Fleece before any warranty consideration. Damage or failure caused by contaminated fuel or debris in the fuel system is not covered on any fuel-system component, including injection pumps, lift pumps and sending units. Labor and installation expenses are excluded, as are normal maintenance and wear items, damage from improper installation or lack of maintenance, repairs by a service outlet that is not an Authorized Fleece Performance Engineering Dealer, use of parts that are not genuine Fleece Performance Engineering parts, accident, misuse and alteration, acts of God, and economic loss or extra expense such as towing, storage, shipping, lost time and inconvenience. Warranty concerns go to your Authorized Dealer or to Fleece Performance Engineering on 317-286-3573.
Warranty terms are set by the manufacturer and may change. Full details and claims are handled directly by Fleece Performance. Contact us if you need help with a warranty claim.
