Hey Burners!!
SO! My trans is having trouble turning HP into guts at the rears.
I'm having to throttle shift the transmission to up the gears, and it will drop down a gear at the first sign of needing to work a bit.
This dilemma fades in and out. Some days it all works great, then there's a slight hint of extra delayed up shifting, then a day or drive or two later, it will throttle to 2800 RPM and won't upshift unless I pump shift with the throttle. Doesn't take much of a throttle drop to get it to shift.
On freeway at speeds no problems, unless hitting the Grapevine, then it might downshift at 55mph while in OD. No trans light comes on at the OD switch.
As soon as I let off the throttle, the trans readily wants to downshift, even going downhill.
Happens hot or cold.
Replaced FIPL, tuned it to 1.1V-4.5V.... smooth range of V up and down, no drops on meter in between on a hot engine aka properly warmed up.
So the question is..... ***!!???
Bad FIPL in spite of it holding good voltage with the hood up? I changed FIPL because of the description, however, same condition exists with new FIPL.
Thanks in advance as always.
