AOD Transmission Idea

February 02, 2011, 03:04:00 PM

Well driving around in the snow/sleet/rain combination in New England these past couple days made me wish I had a couple things. Traction Control might help, ABS brakes would help too, but a Transmission that holds a gear to engine brake would be even nicer.

Now a stock AOD on the gear selector has OD, D, and 1. Can anything be adjusted to make D hold second gear, or for 1 to hold second gear? Like going down hills and stuff in 1st isn't really an option. I was just curious if this was possible with some sort of easy adjustment.

If the lever is on D or OD on the selector but you are driving at say 30 mph or so, you're not in overdrive, you're in 3rd gear. If you pull it down to "1", it will go to 2nd gear. If you continue decelerating to say 15 mph or so (depending on how tight/loose your TV cable is adjusted and your gearing) it will then grab 1st gear. In each case it will actually engage the OD band as well I believe, or whatever component it uses to engage lockup. But if you pull the lever down to "1", it will lock the driveline directly to the engine, no slippage from the converter, so you'll definitely get engine braking.

Epoxy mod valve body. I have one in mine and can get any gear manually. It's pretty fun to shift it manually, especially with a column shifter

So in theory the car is already set up like I want. If I'm going 30ish mph and I hit first, the car is only going to shift down into second, right? I never tried it, because I thought 1 was simply 1. I figured it would drop the car into 1st at 30 and It'd more than likely blow first gear.

Now I don't know much about transmissions, but putting the car in first will will use the OD bands? Can you explain this? If the car in fact will shift into 2nd at 20-30mph going from OD or D, then that is what I want, I don't need any modifications.

Back when I was a teen, I would take my couguar (86 5.0 w/ AOD) to the 1/8 mile track. The guys there taught me to shift down to 1. When I was read for second gear, shift up to D then back down to 1, then back up to D for 3rd gear. On 1/8 mile tack only needed the first two gears if I remember. If you want to experiment. Try it out in low speeds to where you won't hurt anything form.

Thanks for the input. Sounds like the same thing they were saying. You were just using it to speed up. I can't beat on my car... It'll break. :/

Well while chasing down my EGR/sputtering problem, I tested this. While going about 27 I shifted into "1" on the floor shifter, the car shifted into 2nd and as I slowed more, shifted into 1st gear. So in all honesty, the car does what I wanted, I was just too scared to try it, lol.

Early C4s had a D and a green dot. The D started you out in second gear for snow driving and general grandma and grocery fetching activities. Shifting into "green dot" gave you all 1-2-3 gears.
This useless tidbit brought to you by CougarGT.

Yeah speed governors and accumulators, etc will prevent the transmission from trying to actually apply gears before the right speed range is reached.

That epoxy mod sounds great but then you lose OD lockout. Naturally not an issue if you have an "A" or better servo and a wider band, but personally I wouldn't want it instantly dumping itself right into OD every freakin' time I go above 40-50 mph and let off LOL. Just my own OCD-ness. I gotta make my own VB and instrument panel surround that has 1, *2* and D and OD positions. Then it will literally have all of em. :hick:

Yeah, the epoxy mod would probably be the best fix without going to a newer trans. I guess you can do the shuffle, but it will wear it out quicker. I personally do it alot just for fun at 50 to55 mph just for fun, but I also have a new engine and am looking to upgrade to a stick, so doesn,t bug me much.

It's not bad. Just keep your foot in it

. I should have mentioned that I have an A+ billet servo and a 2" OD band. It's pretty much a requirement with and epoxy-mod valve body.

I've never had a problem with OD wander *but* I do live in Chicago, which is flat as a pool table. I could see it being a problem in a hilly area, maybe.
