For Those With Tci Flexplate Please Help
i have tci converter and tci flexplate. i have trans bolted up.
tci flexplate come sout a little farther then stock so it seems.
with converter up in there and trans bolted up theres a space of about a flat head screw driverbetween flexplate and torque converter. is this correct?
or is the toqrue converter not on correctly. also the torque converter spins.but not easily.
also
the converter measured 1 inch depp in the bellhousing

Hmmmm.... by that description it sounds correct.
Meaning that if the converter is seated it should be about an inch or so back from the engine mounting flange of the bellhousing.
Chris... did you check to make sure that the flexplate is installed correctly... engine side towrds engine?

Just put in the TH400 yesterday with the TCI flexplate bolted up to the motor...I have the same gap between the TC and the flexplate as well.
haven't put too much thought to it "yet" as I have to go buy some 7/16th TC bolts.
The pic is a lil dark but shows the gap between the two.

Yes if any paint is on the flex plate or the converter it should be removed from the mounting pads. tight bolts can be loose after a while if you dont

So, youre saying by grinding off the paint on every mounting surface (tq converter to flex plate, flex plate to crankshaft mounting surface, etc.) will resolve this gap issue? Eh, maybe a litte, but I dont think enough to get flexplate and tq converter to actually seat against each other. Looks like we have to put some shims between the two.

Wouldn't help at all in in fact it would make it worse, if you are taking "material" away from the flexplate...but we digress.
What to do about the gap between the converter and flexplate...you'd think these transmission shops and sponsors would be able to answer this immediately....
Any members know how to remedy this situation?

The spacing sounds corect but it should spin easily

Found some tech info off another site about the converter gap
So if its 3/16ths or greater, shim it with washers to get it below that spec?

Check the gap between the converter bolt pads and the flexplate. If there is too much space between the two, the converter will be pulled slightly from the tranny and cause pump damage. If more than 3/16ths of an inch, shim up the gap with hardened flat washers and buy slightly longer GRADE 8 bolts.
Another consideration. Remove the paint from the nose of the converter and apply grease to this location. In addition, remove any rust or dirt from the crankshaft hole where the nose of the converter fits into and apply grease there, too. Not doing this can cause the converter to not line up properly and bind when tightening the converter to the flexplate. The flexplate is just that... A flexible plate. It isn't rigid enough to force the converter to line up properly should it bind at the crankshaft floating point. You'll know if this happens immediately upon starting the engine. A severe vibration will be intuitively obvious!

We'll measure it first. I cleaned out the snout on the crank as well as the crank threads with brake cleaner and cleaned off the TCI adapter ring with brake clean as well....so all should be great. Doubt the grease will help.
I could understand if the converter was dragging when we spin it, but it spins freely...remember when we were lining up the TC to flexplate bolt holes, it spun real smooth, so i'm sure we are good without having to grease it.
Time to get my mandatory 3hrs of sleep before waking up for work

so if it doesnt spin frrely like rolle around on its own then i obviously dont have it in right correct? but as i was stateing earlier. i have the same depths as you on spacing between everything. i cant afford for anythign to break at this point so what do i do?
