I have done further research in stall testing and you are right in that you should be able to determine the stall speed in 5 seconds or less. There has come to light another caution, If during the test the stall speed exeeds 2100-2200 rpm the test should be ended immediatly as it now indicates a slipping clutch or brake internal to the transmission.AGAIN I MUST WARN THAT THIS TEST MUST BE CONDUCTED UNDER VERY STRICT CONDITIONS. After reviewing the possible outcomes from improperly doing this procedure I cannot ask any members of the list to risk their cars. This should be done only by highly qualified mechanics who have years of experience in testing and rebuilding automatic transmissions. I ask that the venders and other experienced persons ONLY help in determining the correct stall speed spec and the proper procedure.Btw this procedure is used by racers with a trans brake installed in a modified transmission to "launch" a car with an automatic transmission.In these circumstances they have a scattershield installed to contain the pieces so they don't go through the console and land 1/4 mile down the road. David Teitelbaum vin 10757 BTW the stall speed in my automatic tested out at 2050+- 50 rpm. --- In dmcnews@xxxxxxxxxxx, "DMC Joe" <dmcjoe@xxxx> wrote: > David, > > Concerning the following statement on your "stall speed test": > > "release accelerator pedal smoothly ( don't hold to floor for more > than 20 seconds)" > > I did some research on this test and wanted to let you and any other > Delorean owners who consider conducting this test that according to the > "Auto Service and Repair Manual" published by Goodheart-Willcox Co. > indicates the following: > > "When stall testing, never keep the accelerator pedal in the full throttle > position for longer than five seconds.
