yeah i wasn't really thinking about WOT, but now that you mentioned i remembered how bad that stock tuning was in the 2-3 shift at WOT... i can definitely see how manually shifting that would help a lot

If you did any mountain driving with 15k to 25k gross combo weights, you'd wish it did. There is just WAY to much heat produced by an unlocked TC at full throttle for even the biggest cooler to take away - flow rate is limited by the pump, and that limits the amount of heat that can be taken away.

Ok, I am feeling a little better about the trany.
When I am going between 30-40mph at a constant speed and give it some throttle the rpms will go up 300-500 rpms but not really accelerate the truck very much, is this normal torque converter slippage? I am used to standards anyways so it will take a little while to get used to the big automatics.
Other then that, it seems to act normal to me.
secondarychaos posted a link to a transmission modification kit toward the begging of the thread, is this something any of you guys have done and how involved is it?
Thanks for all the help, greatly appreciated.

In the diesel the engine has enough torque that when the torque converter locks the truck accelerates AND the engine slows down. In an Escort, the car accelerates a tiny bit and the engine slows down. There's a lot less torque in the Escort engine.

E4OD= Electronic 4speed Overdrive.
The locking TC can feel like a gear change depending on
how the trans is setup (locking pressure), and how much
torque multiple it has. Locking the TC removes the multiple.

i havnt had any experiance with the ese kit listed in the begining but all the feedback so far has been good. the majority of the springs you get are for the valve body, thats nothing new, almost every shift kit you buy replaces them as well. the big difference in that kit is the elimination of the electronic pressure control whic is the main issue with our fluid system in the trans

Not to big of a deal if you run one tune.
Big deal if running a flip chip. (my opinion)
Trans is much more consistent with it.

i run one tune with mine and if i want to make the epc angry i can by simply "adjusting" throttle at different times... no different then if you were just driving along and hitting small hills or in minor traffic. the epc is annoying.
