E4OD waits too long to shift out of first

[Powerstrokedogg]

the tranny doesent want to shift out of first, it waits for me to go over 25 MPH (and i have to let off the throttle) to get it to shift to second i have adjusted the TPS so i have 1.1 volts and still no change


can anyone point me in the right direction

thanks

mine did the same thing before the TC came a part on me and puked tranny fulid . chage the filter see how much metalis on the magentin side the pan . oh by the way when mine puked the trany fulid and it caught on fire frome hot exhaust pipe

My truck did the same about a year ago. I changed the fluid (80000 miles)and replaced the filter. Problem stopped.

i just put a different engine in the truck, it shifted fine before the swap [img]/ubbthreads/images/graemlins/shrug.gif[/img]

Check and clean all the plugs on the tranny and on the computer.Is your tach and spedo working properly?

You should check the FIPL reading. It is probably off a bit. Tim

Here are the settings:

Fuel Injection Pump Lever (FIPL or TPS) Check and reset procedures.

The FIPL is a fundamental part of the operating system of the E4OD transmission. It aids the Transmission Electronic Control Assembly in determining proper shift points in relation to throttle position and allows the computer to determine both WOT for downshifts and idle position for TC lock and unlock.

Resetting or replacement of the FIPL can solve many of the problematic shifting issues with the E4OD trasmission mated to the 7.3L IDI's.

Below are simplified procedures that can be used to adjust/reset the FIPL.

Hook up the negative lead of the volt meter to the battery ground and the positiove lead to the center GY/W ( grey/white wire which is the FIPL signal wire, I use a paper clip up the side of the wire in the connector. The FIPL must be attached to the wiring harness. Engine low idle speed must be set to specs prior to adjusting the FIPL.

Engine off key on........
With a warm engine, key on, engine off measure the voltage at the GY/W wire, if adjustment is required loosen either the bracket with bolts or just use the slack in the Torx screw holes. Now gently rotate the FIPL until you get some where between 1.05V and 1.1V. then tighten the torx screws or bolts which ever you loosened ensuring no movement of volt setting . Rotate the throttle lever to WOT see if you get 3.8 V but not more than 4.3 V.

The FIPL mounting bracket can be moved but ensure it is centered for a good rotation. Any adjustment should be made by only rotating the FIPL. If a new FIPL is required, check tang engagement as you take off the old FIPL and then make sure that the tangs in the new FIPL engage the throttle lever properly.

The closed throttle voltage: 1.1 V, .........wide open throttle voltage: minimum of 3.8 V but not more than 4.3 V.

i already tried that, i can turn the TPS down to .4 volts and it still waits too long to shift

the tach is working fine, but just to be sure the tach sensor wasn't the problem i swapped it with the one off the other engine

i have it set arround .5 volts right now, i kinda noticed its doing the same thing in all gears but first is the most noticable, almost like my governor is sticking(now i know the E4OD doesn't have a govenor)

could it possibly be the speed sensor on the side of the tranny ?

Well Dogg,
It shifted fine before the swap. So, What I would do is clean and check all the plugs and terminals. I'm wondering if you still have the TPS from the old engine. If you do, I would swap it with the one you have on there now. Or, is it the same one? When adjusting the TPS, does it make any difference in the shift behavior?

[Powerstrokedogg]

well my new engine is a 6.9 so i had to swap the TPS setup, when i adajust the TPS it doesn't affect how fast it shifts out of first, but it changes how fast it shifts into third, fourth and TC lockup
