If I run a 2400 stall converter in the AOD but run about 1800 RPM at highway speeds wont I be slipping the converter creating a lot of heat. I need the stall for the cam. What are you thoughts?
it depends It depends on your input shafts. If you keep the stock 2 piece input shafts you will be fine. On the stock setup the big (outer) shaft is used in R,1,2 and it what is connected to the stator. The inner solid shaft is for 3rd and 4th. It is splined directly to the inside of the converter and then to the 3rd gear clutches. When you are in 3rd and 4th gear in the AOD you are always locked up. There is no way to unlock it unless you change to a one piece input shaft from art carr or Baumann Engineering or someone like that. Hope this helps. Chad
So, you are by-passing the converter in 3rd and 4th gear--ie-it its a direct connection to the clutch pack because the converter is bolted to the flexplate? If memory serves GM overdrives are not setup this way, correct? Thanks again for you input
Correct. With the AOD 3rd and 4th gear is a direct hookup like a clutch in a manual trans. Ford has changed this in the newer trannies. I know the AODE has a solinoid for tcc. All of the newer gm trans have a solenoid also. I know the 4L60E has a solenoid which is based on the 700r4.
I think they started in 82 or 83. I had a 91 crownvic with the AOD in it. I think 93 was the last year of the AOD. The newer one you get the better. Say like a 91-93, they have improved oil passages and such. I learned alot on this were site when I first got my expolice car. Http://www.baumannengineering.com/index.htm I have a trans go shift kit in it. I worked great. My AOD went out at 210,000 miles. I had a local guy rebuild it with some AODE parts (3rd clutch pack, 2 inch overdrive band, A servo). The guy used a different case so I bought another transgo kit to put in it.
I need to add somthing to the OD operation. With the trans in lockup all the power goes thru the OD band as well. This is why the OD fails so often from a burned out band. This band also keep the trans from free wheeling in 2nd and 3rd gears. Many shuffle shift an AOD and end up burning the OD band because the trans won't release the OD band fast enough under those shifting conditions and results in the engine trying to pull thru two shifing conditions at the same time for a small amount of time. This trans behind a Blower also need the benifit of a larger servo and even a wider OD band.
You can put the 2 inch overdrice band from the AODE in the AOD. The AOD band is only 1.5 inches. You will also have to change the housing the band goes around. I used to know all this stuff when I had my AOD. The 3rd clutch pack from the AODE will fit in the AOD also. I would put the "A" servo in the AOD also.
