Thanks, Rayo, nice post.
I can totally believe it; looking at the velocities involved, there's no way it was a 2-1.
When I upgraded the 96 Black Cougar's still working tranny, TC, and driveshaft, the PI intake and tune I had done to the car had completely wasted the 96 tranny, TC, and driveshaft.
The one way clutch came out in pieces, but was still hooking up somehow; it had issues, but not like you would think, looking like that, lol.
I upgraded to a PST aluminum DS, DirtyDog TC, and an 02 tranny, jmoded.
I'm having no issues at all now.
So, is the chance of failing a later model
4R70W higher doing a 3-2, or a 3-4 wot?
There's a difference in the 3-4 shift in the later trannys...
My big problem is:
The 3-2 happens when you dramatically increase
throttle; the 3-4 when you start to decrease
throttle, without the "OD cancel" function engaged.
It's a lighter shift that full WOT, but it's still pretty high.
Enquiring minds want to know, 'cause I'll likely be doing one of those two things, every work day, for the next 10 years at least, in the same place, merging with the same traffic.
(In an MN12, god willing.)
Legal is 55 mph; it's never
moving at that.
It's not quite
"merge properly or die" but it's close.
I've never slipped one of the new ones like I did the old tranny, despite having much more power.
