light/ normal throttle is almost always while in 3rd gear mid way through the gear range
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
i don't really remember how my truck ran stock but... with my custom tunes it will NEVER lock in 2nd gear... once it hit 3rd it would lock...
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.
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?
I have read that the diesel converters are different then the gas ones but on my 98 escort wagon I don't notice that type of action
Diesel and gas torque converters are different, but the theory of operation is identical. What's different is in the tuning and strength, but they all work the same way.
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

yea that is completely normal, when the TC is unlocked it's supposed to do that
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.
if you're talking about doing a valve body?? you take out the stock one (first thing you see after you take off the transmission pan...) and you throw in the new one
