You might check to see what fluid they will be using. When my wife ask for 236.10 they told her they only use one type. Same fluid as in the newer 7 speed 722.9 transmission which requires 236.14 IIRC.

From what I have read the newer fluid is lower in viscosity and does not work well in the older 722.6 5 speed which called for 236.10 fluid.

They claim it is "backwards compatible" but who knows...
