Question Schaeffer's ATF??

[mike.germann]

Anyone know which type of Schaeffer's trans fluid I'm supposed to use in my 99 SD with the 4x4 (automatic) 4r100?

I googled it, but the Schaeffer's website didn't help. I'm lost between all the types like Dextron, Mercon, I,II,III,IV etc.

Which type of Schaeffer's and WHERE to get it?

Thanks

depends on if your tranny has been rebuilt or not.

use PLAIN ATF or Mercon III in an OEM tranny. you do NOT want to run Mercon V in OEM trannies. the oem clutches do not like the additves in Mercron V.

there is a dealer locator on scheaffers website.

better use plain, dumb, generic ATF at regular intervals instead of expensive stuff.

check with the re-builder, but it should be Mercon non-V

My trans was recently rebuilt. I'll check with the rebuilder.

x2 on the idea for using the cheaper fluid.

With the luck I'm havin thus far, I'd have to drain it and start all over, or something equivalently ridiculous. My wallet has already gotten plenty of exercise since buying this truck.
