Hi all,

In a previous post, it was suggested that I do a Torque Converter Stall Speed Test -

I had requested more information regarding this test, but to no avail.

In any case I did some research and now I have a couple of questions.


1. Should I even try to do the Stall Speed Test - From what I can tell it could actually cause problems with my Disco.

• Do not perform this test on vehicles that are equipped with a traction control and/or ABS systems. The inputs of a partially opened throttle, brakes applied, and no detectable movement by the wheel speed sensors will at best set a code, and at worst cause damage to the vehicle. Also, on electronically controlled transmissions that use vehicle speed sensor to determine shift points be prepared for a code to be set if you perform a stall test

I am not sure if my Disco has traction control, but it does have ABS. I am therefore a little unsure if it would be wise to do this test.


2. If I do the stall test as described below, what is the "Specifications" for the Stall Speed on the 94/95 Disco?

• Start the engine and place the transmission in drive while holding the brake pedal under firm pressure so the vehicle does not move. Then push the accelerator to the floor while holding the brakes on. Note the maximum rpm the engine reaches. This is the stall speed.

Thanks for all input and thoughts,

In Peace and Agape,
Trav...

 

That stall test sounds to me like it would be a engine wrecker. If you max it out. Yikes

 

Just change the fluid and filter and see what happens.
Its going to cost you $50 and a days worth of your time.

 

If you perform such a test with an older transmission, you can effectively cut off most of the remaining life of the clutch packs. Please do the filter and fluid change before anything else. I have 175 K on mine and still shifting and pulling fine.
