alright, as some of you may know i have been getting in to autox racing. And having an automatic is somewhat the disadavantag in this sport. My probelm with some of the longer courses is that i max out first gear. I don't put the car in 'drive' because i don't want the car to shift halfway thru a corner or some time when i need the power. So i have been always racing by just putting it in first and leaving it. Now for my questions. Is the automatic tranny in my stang have the ability to and be able to withstand me shifting it from first to second, then back down to first. I know it will let me upshift no problem i am just unsure how safe it would be to down shift. I don't want to cause any problems and i wouldn't be shifting it down to first at like 45mph or anything crazy like that, but more around 25-30mph~ would that be safe? once again i don't want to cause any damage, so if you are just guessing please don't i would rather hear actual fact, then guesses. thanks in advance.

 

Stall converter and tranny cooler.

 

so your saying i will break it without the above parts?

 

Well its deffinetly added stress that can be avoided. Sure, breaking it could be down the road. If you are doing something like that, you should have a tranny cooler at the VERY minimum and its a cheap mod. A stall is going to help your car perform to the standard of a manual.

 

alright, thanks. i think i might look into a tranny cooler then before i do any downshifting especially since my car has 82k miles on it, i would rather preserve the tranny as much as possible rather then have to replace it.

 

Your gonna need the stall and the cooler are a must. I'm worried about that shifting your doing may want to look into a built tranny with rachet shifter. Throwing your car into 1st at 30mph is not smart. Did it once at 15 mph and it jerked pretty bad. Dont be surprised if you wake up to a broken tranny soon.

 

no worries i have never done it, that is why i came here to consult people who would know about this stuff. Do you have any sites for the cooler and the stall? I know you know your stuff with these auto trannies so help would be appreciated.

 

I learned the hard way unfortunitely. Go to http://www.summitracing.com/ they have tranny coolers for our cars. The bigger the better especially in your case. They are in the price range of $40 good brands are B&M or Ford Racing make sure its the steel plated ones and not the ghetto finned ones.

 

I'd be terrified of fragging a planetary gear. They're strong but not that strong. Here's a thought... why not get taller rear gears like 3.08's so you won't have to shift much at all. give yourself more (RPM over time) and higher speed at the cost of a little acceleration rate. Then you don't have to go smacking back and forth between 1st and 2nd which will destroy your tranny.

 

i like that idea, but have a V6 not sure i can sacrafice the little and i mean little bit of acceleration i have . I was however doing some thinking and thought of doing the opposite of what you suggest. Get 4.10's and do the tuner plus an underdrive pulley and hope that that is enough added pick up(mainly from the gears) so that i could just race in second gear the whole time. how does that sound?

6 of one half a dozen of the next. it really would depend on your minimum speed. Even in 2nd you're going to have to go around corners but if you can keep the speed up so your rpm's don't drop too far then the 4.10's route is a decent idea. UDP's... I never liked them. Not nearly enough benefit to justify the cost. See if you can find a hotter cam for your car, that'll pick the power way up in the higher rpms. Or you could do a MM coil over conversion all the way around and lose probably 70lbs off the car which will help acceleration more than more power.
