Race prep 5r55e???

[umbrobryan]

Welp, we just finished up the 2011 TREC series and its time to start rounding up thoughts and ideals for the 2012 series.

I'm currently running a 99 4.0 ohv with a 5r55e, 4.10's and 31"tires. I put a shift kit in the trans earlier in the season and it felt better but the truck is still a gutless wonder

Plans for next year need to come together sooner than later. One forsure thiing is power needs upgraded so I will be dropping a 4.0 sohc in it.

On to transmitting power to the ground. I've thought about putting a manual in it but I don't want to have to clutch during a 2+hr race. Its gonna be a last resort if it comes down to it though.

What I would ultimatly like to do is upgrade the 5r55e with all around better internal components. The trans in its current state just feels like its trying so hard to go fast but it is redicuously slow. Another issue id like to solve is the fact that it holds 2nd forever and then will eventually shift to 1st if it feels like it.

Now I've been wanting to also put a floor shifter in it for easier 1-2 shifts but I'm not sure if that would help cause it will still only shift when it wants too. I was also wandering since its electronically controlled if I could wire up a switch, like a paddle shifter to control the trans.

If anyone has any advice, I am open to all sugesstions and options. Thank u in advance

you can put a c4 behind a sohc 4.0 and build it with a manual valve body and an art-carr shifter ect. Thats what a lot of desert guys do

The C4 might be frowned on if some found out I was using it. I talked some with the fellows last night at Macgyvers and they were giving me shit b/c I said I didnt want to shift.

I geuss that Makes me lazy. Might end up considering after all. Id prolly save some cash going that route also.

Still up in the air!!!

i am working on a similar setup but bigger, just dont have the time to help.

they dont sell shit for this but can still set you up tuning wise for the trans.


a built c4 with the cammer is a good way to go and you should be able to legally do it as it was available in the trucks originally. adapting it will take a bit with some cafeful parts selection though. best way to go for racing but lentech was working on a way to put the 4r70w behind the cammers.


the 4r70 is definitely the best way to go, i just dont see it being cost effective...but if you boost power it may be the best bet.

I agree, the 4R70W is a great trans. IMHO, the best 4 speed auto to come in a Ford.
