ok so i am still curious what my problem is with out a teardown but i think i am just going to eventually replace it with a granny 4 any one else made this swap what did you have to buy i know it is pretty straight forward and i shouldnt have many problems i am curious about drive shafts though i know i will need clutch pedal, flywheel, clutch kit, clutch master and slave cylinder or linkage assembly(depending on the style bellhousing i get) any one have any suggestions for me i have 3L55 rear 3.54 front and will eventually run atleast 35s maybe as much as 44s

yo,
Here ya go;
E4OD Shudder; "...If the shudder occurs a) during the 3-4 or 4-3 shift at HEAVY throttle, or b) at 40mph in 2, OD OFF, and OD, or c) at the same RPM in every gear, or d) coasting, cruising, or in R, or e) during extended light braking, then it is NOT TC clutch shudder;
The following is a list of common vehicle concerns that have been misdiagnosed as torque converter clutch shudder. For diagnosis of the following items, refer to the appropriate sections of the workshop manual and the Powertrain Control/Emissions Diagnosis manual (PCED).
Spark plugs - check for cracks, high resistance or broken insulators. Plug wires.
Fuel injector - filter may be plugged. Fuel contamination - engine runs poorly. EGR valve - valve may let in too much exhaust gas and cause engine to run lean.
Vacuum leak - engine will not get correct air/fuel mixture.
MAP/MAF sensor - improper air/fuel mixture. HO2S sensor - too rich/lean air/fuel mixture. Fuel pressure - may be too low. Engine mounts -loose/damaged mounts can cause vibration concerns.
Axle joints - check for vibration..."

Have you checked for Diagnostic Trouble Codes (DTCs) yet?
Do the Self Test;

I run it around to heat the engine up and shift thru all gears incl Reverse.
then; turn off all accesories/lights, etc.
Do KOEO portion first
For Key On Engine Running (KOER) portion, the engine has to be @ normal operating temp.
Post any codes found here or look em up in my broncolinks.com site.

I think I know what torque converter shudder is and dont think I am having any I could be wrong though. I dont have any codes set koeo, koer except for the egr system which has been bypassed. The original problem which I quoted below is the torque converter bogging the motor down and stalling it out when the truck is placed in reverse or drive until it is in gear and you power brake the truck then it is good until it either gets to overdrive or you put it back in neutral. Then it bogs the motor down again. No worries though I got a used one that hopefully works better than the one in the truck. I am always trying to learn something new.yo,

Identifying the E4OD/4R100 Solenoids - Page 1
Solenoid Identification; "...There are three OEM style solenoids for the E4OD/4R100 as shown in the picture to the right. Additionally, Transtar offers two additional solenoids which add a LOCK-UP DELAY to the OEM model; 89-94 36420R 36420AR First design plug; 95-98 36420BR 36420CR Second design plug..."

"...Be careful with the different connectors. The early E4OD solenoid packs had diodes in built into the pack to prevent the voltage spike for the collapsing magnetic field of the solenoid from cooking the computer. In the later (I can't remeber which year, I think 94?) Ford removed the diodes from the solenoid pack in the trans and added protection in the computer. If you end up with a late solenoid pack and an early computer you will likely be buying a new computer. Going from memory which is a couple years old now, the early solenoid packs had a redish orange seal in the electrical connector on the transmission side, the later solenoid packs without diodes have a green seal which goes into the vehicle side harness. I the plugs don't easily plug in wrong, but if you really try you can..."
