Ok this may get lengthy but I will explain I know my truck! And I am so baffled by this! Maybe somebody can explain!
I Again it is a 94 F 150 with a 302 engine 4x4
Transmission is an E40D (Code on door is an "E")
The truck has 160 thousand, I got her 61/2 years ago!
Been working on her since!
Anyway, after driving the truck hard (70 - 75) Turnpike speeds
more than say 30 miles, get off the pike or other highway
come to a stop, engine still performs as normal, while excellerating around 12 miles an hour shifts out of 1st gear and kicks, kicks hard (replaced u joint because of it)
Drive say a week or so doing it constantly just 1st gear.
at this time when you put trans in Reverse truck would bogg down!
Then the kicking goes away, shifting is smooth again! NO bogging in reverse either! a month or so would go by or I had to drive her hard again!
Then the kicking starts up and the bogging in reverse!
off and on all of fall and winter!
My first attempt at the shift solenoid (found out I got wrong part)
I drained all tranny fluid, removed the solenoid pack (found out right part) (DID not get new part yet!)
I repeat have not gotten NEW part!
Now the system is drained And the solenoid pack is removed.
Realizing I have no choice but to put it back together it was a Sunday!
Recycled the fluid due to the fact it only had about 50 thousand miles and looked good!
Filtered the old fluid and put it back in the system!
started truck warmed it up ran thru all the gears to get fluid flowing!
Including reverse, NO STALLING and no bogging down!
Ran truck Monday to work 22 miles, Trans hasn't operated this smooth since I bought the truck!
Ran it from 2-26 to 3-6
Then I rechecked the fluid!
To realize it was low! added a little fluid! TRUCK started kicking and stalling in reverse!
Tonight drained some fluid back out to see if it would correct itself!
Running thru the gears it dies in 1st, 2nd and reverse with foot on the brake and in that gear!
Fuel pump and system are not even a year old! it is NOT a fuel issue!
Any suggestions short of driving it off a cliff??? lol
Sorry took me so long to repost internet issues!
