Thanks.... stated the wrong spec....
One side note.... I have heard, never had it substantiated, but looking at it, the Torqshift 5 speed auto (5R110) was actually produced for Ford by Allison. But due to the agreement between GMC and Allison they could not provide Allison transmissions to Ford. Ford spec'ed out what they wanted, and a Ford transmission was built, by Allison. Again, this is just what I have heard, but have not seen it in writing. But if you look at a 5R110, it does not look like any Ford auto that I have seen...... but it looks just like a Allison.
I tryed, but he wouldnt listen, its his truck not mine
Thanks Mike!!!! THey are a tough transmission, and I like the fact they were designed to tow, and still use all 5 gears..... not just an OD lockout..... a far superior transmission to be in a truck...
TorqShift Transmissions use Mercon SP transmission fluid- nothing else
Mercon SP or the Mercon LV fluid that now has replaced the SP.
