Shift Kit and Tuner
Hey..
It was suggested to me that if I put a tuner on my 05 fx4, that I should also put a shift kit in. I was doing some research on here and another opinion was that if you put a tuner, it acts like a shift kit. Because of this, it was suggested that I don't put on a tuner AND a shift kit because it may cause a problem having both.
Any thoughts?
I have a 05 fx4 with 3.73. Everything else is stock.
I just want something to wake the truck up.. I'm not racing and have no inclination to do so.. Just like to have the extra power when I need it.
Thanks again folks...
Chris

Do both, but don't let the tuner adjust the trans. I had used my tuner to bring up my line pressure, and it was ok. I installed a factory tech valve body, and it's a major difference. The shift kit will help extend the life of the trans by meshing the gears faster so they spend less time on the clutches. They also provide more fluid to the trans (volumetrically), so it runs a little cooler, the tuner can send more pressure, but it seems like that is hard on the pump.

I suppose this is an extensive process?

The shift kit is a smart move.. especially with these trannys... not known for durability... especially around 45K miles.....it only takes a few hours to install a shift kit... its widely used by taxi's and police cars... it prolongs the wear and tear for those cars which get abused....i installed my kit when i had my tranny rebuilt at 49K miles...i'm assuming you are going to adjust the shift points (reason for your tuner)... im told by our mechanic at the police station.. he orders our vehicles tuned and with shift kit... he said he would never do a tuned veh. w/out a kit... hope that helps

You said a shift kit takes only a couple hours to install.. Would any local mechanic most likely be able to do this? Should I be looking for something special?
From what I'm reading, some think it's worth putting a tuner and a kit, and some say they are 'redundant'...

You WILL damage your truck if you install both (and use the transmission tuning of the performance tuner). Guess I wasn't clear enough.

I know it's not a ford, but on my 06 jeep liberty, I read on the jeep forum to do both, I got the trans go shift kit and tunner. The tunner only did so much, but the trans go made a huge difference. Some of the guy's on the forum have been running this combonations for a few years now and it's the ticket on and offroad with no addverse effects as some guy's are at over 100,000 miles. This is a jeep and not a ford, so I can't tell you if it will hurt your tranny or not, but I can tell you it made a big difference on the kj, I even noticed a slight increade in mpg, it holds low for prolonged periods offroad, especially down hill. Tranny runs cooler and the shifts are tight, it feels like a different rig. Thats one of the beefs with testers of the 150 in the offroad mags, the tranny sucks up to much power, it doesn't feel like the engine has 300 hp. Part of this is due to prolonged shifts. I would say whatever method would improve shifting, would be a worth wild upgrade. I don't know if doing both would hurt the fords tranny, so I would listen to the experts, cause tranny's aren't cheap.

almost 10 years of police work in L.A. driving nothing but Fords pounding the engines and trannys tell me something.. Ford engins are superb.. Trannys cant take a beating without mods... All of the cars we used for patrol while I was with the L.A. sheriffs dept (which by the way carries the largest patrol car fleet in the country) and with my current dept. El Monte P.D... are tuned AND have a shift kit... Its the norm in the industry.. as well as taxi companys... which all have us abusive drivers...
Hope this helps

I understand being a die hard Ford Fanatic its not nice to hear negatives about a product we love.. But the truth is the truth. Especially for the 04 year models... Anyway... Im glad you SEE and KNOW otherwise... You must be driving something other than an 04 with 45k miles...

). I can only repeat what I know. It would be interesting to see what a tuner manufacturer would say about stacking these products.

I was curious about this same issue about a year ago. Fordtrkpuller replied to my original question about running the Edge tuner with a shift kit after talking to the techs at Edge. I believe Fordtrkpuller is one of the gents from Dicsount Power Parts who sell the Edge tuner here. Here is the post, my question appears on page 4.

Needless to say, I have not installed any of these products yet, but hope to have the funds to do so this summer.
