2.4L swap into 91 daytona

You cannot select something you don't want. Have you ever tried to put an A413 into 1st gear at anything above 35mph? 1st won't engage. There are built in safeguards against that. You really think the tranny PCM is THAT perfect???

hmmmmmmm, didnt think it about that, cool deal, ill give it a shot

The reason 1st won't engage is simply because of the way the mechanics of the tranny work. The governor is spinning too fast for the valve to open to allow fluid to flow to that circut. If you have a MVB it WILL engage 1st gear, BUT, unless you have a custom one from "torqueflight" on here it wont rev because it doesn't have engine braking built in to that gear.

On the 604 the TCM sees that if the selected gear will put the input and output speeds out of range, or the engine speed out of range, it will not select that gear. If we figure out how to actually manually control the transmission though...it more than likely will go in to gear...no matter what!

thats what i was thinking. so far for the shifter im thinking of modifying a b&m or using momentry switches with latching relays

I would rig up some switches/buttons to the underside of a normal 5-speed shifter. Though now that I just thought a little more it might not be easy. The front to back stops are in the tranny and you might revert to 2nd every time you move the shifter out of a gear.

I am realy interested in this. what is the tranny numbers? I want to swap my srt4 to a 4speed auto and Use megasquirt to run it all. I was thinking about paddle shifters. what info you you have on the trannys?

We are reffering to an A604/41TE. The one in this thread is backing a 2.4L DOHC engine that has been turboed. Basically the same thing you would find in a lot of the Turbo PT's. They can clearly withsatnd stock power, but how much beyond that in non-modified form, I don't know. Modified they can take quite a bit, but they have to be built right, which can cost a pretty penny.

yeah i dont know how long the a604 is going to last w/ the power
