Shift kit

Has anybody installed transgo part number SK AWF21 shift kit? I'm a fan of these kits as they improve the performance and lifetime of auto trannys, but Ive never installed one in a front wheel drive car. They typically cause a firmer, harder shift (which is better for the trans, although this is counter intuitive to most who think shifting should be smooth and soft) and not sure how that would feel in a front driver.

Anyway, a couple observations. Apparently the 6 (mines a 2014) has a Aisin Warner AW6A-EL transmission. I had assumed this was a newer transmission with all the skyactiv hype about it, but it appears to be the same transmission ford and others have been using since 2005 in the fusion and other models.

this is a general description from transgo webpage:

Fits "Aisin Warner TF 81SC" 2005-2006 Ford Fusion & 500, 2005-2006 Mazda 6, 2006 Lincoln Zephyr, 2006 Mercury Milan, and 2005-2006 Mercury Montego

Includes (2) drop in Solenoid Regulator valve assemblies, TCC/Lock Up Boost valve assembly and parts for renewing Pressure Control Solenoids. Convenient drop in valves!

Addresses Rough shifts, Bump-Bump downshifts above 30 mph hot and Part throttle downshift bang; Flares during up-shifts & kick-down, rough coast downshifts, NO pressure rise, TCC slip/shudder and overall Poor shift quality. Improves and restores correct drivability with added durability.

Installation recommendation: Experienced technician
Transmission removal necessary: No

I would call transgo to verify it works in the newer M6 version before ordering, unless someone has done it and can confirm.

Thanks

Thanks for the question. I never knew they existed and there is an option for my trans as well.

Yes, well worth the money and effort if you can handle the install, which although intimidating to some, is typically not all that difficult. Just take your time and double check all your work.

Yes, firmer shifting causes less slip within the transmission and is better for the unit. that is true. based off of reading what this kit does, sounds good to me. but everything that this kit is supposed to remedy sounds like something a simply panfilter, fluid and solenoid change will remedy. so if you got 60K miles+ on your unit, be very sure to replace the pan filter and fluid when you install this.

Did you notice the drill bits in the picture? Those are for enlarging holes in the valve body fluid passages, not something that happens with a filter, fluid and solenoid change.
