I know that the space between the mounting pad and the flexplate needs to be between 1/8 and 3/16 of an inch. If I measure bigger than that I should put a washer between the converter and the flex plate to correct.


Probably a bad question, but am I supposed to put three washers between each bolt hole and the flex plate to space it right? Just didn't know where to put the washer.

One washer per bolt is what you should use. They need to be placed between the flex plate and the converter pad. Here is a thread I started for you guy's. https://ls1tech.com/forums/showthrea...onverter+vince

That 1/8" inch is the measurement between the conveter "face" and the flexplate, correct? There shoudn't be any space between the mounting pads themselves and the flexplate should there? The more I read about this the more confused I get. I have a feeling those bolts are going to be the biggest problem of the whole install.

The spacing is between the converter pads and the flexplate. The idea is that the converter needs to pull towards the flexplate. This will allow for the converter hub not to bottom out in the pump when bolted up and not cause damage. Vince

Thanks for that explanation.

Thanks for the info............I was 99% sure that is what I need to do, but i just wanted to make sure about it.

Having a TCI flexplate should not change anything should it?

I was under my car this weekend and noticed a gap between the converter and the flexplate too. I also have a TCI flexplate and a Vigilante 3200 converter. I hit it with the impact and the gap's still there. Guess I'll try the washer method. My car's currently down for a turbo install/engine rebuild so I haven't driven it this way. BUT I wanna make sure it's right before I do.

having a TCI FP should not change the clearances.

Also, make sure the pilot is engaged at least an 1/8" in the crank after you shim it.

You mean a gap between the Converter pads and flexplate right? If you used an impact on it and it didn't move, the pads have to be seated, or you would bend the flexplate trying. You should never have to use an impact to seat anything.

This 1/8 to 3/16 gap is measured with the converter NOT bolted to the flexplate and pushed ALL the way into the transmission correct?

Correct!

is the converter pad just the part of the converter that the bolts go though?

Yes, there are 3 "pads" on the converter that stick out to meet the flexplate, and that the bolts go into.

I never thought about this. Of coarse I always make sure the converter is seated to the flexplate, but I've never thought about too much gap. What would be some ill effects. Not engaging the pump, or not engaging the converter? I know when I put mine in there was a large gap, probably 1/4 or so.

i went and did some measuring last night with my stock setup. i have noticed that it depends on which converter pad you measure from. i have my tranny out now. when i measure from the bellhousing to the converter pads is where i see differences. if i don't turn the converter and measure all 3 pads i get different distances. i then realized the converter sags a little bit even when it is pushed all the way in the tranny. from the bellhousing to each converter pad i get a slight range of numbers. mine varied by almost 1/8 of an inch from the pad that was closest to the pad that was the farthest from the bellhousing. this is when the tranny is sitting on the pan (so sitting flat as it would if it was in the car). and yes, the converter was all the way in. i got slightly over an inch on all 3 measurements.

When I installed my Yank SS3600 a few months ago I had never read anything about shimming the gap. I just installed the converter onto the tranny and got the 3 distinct clicks like everyone says. I then bolted up the tranny to the back of the motor and tightened the 3 converter bolts to the flexplate and torqued them to the right torque spec. As far as I can tell everything is and has been working fine. Should I be worried about something breaking?

DanZ28

I doubt it. Most of these things are within spec without shimming, but should be checked to be sure while your there doing it.

my gap scared me a little, but i called an f-body shop and they said it was ok. It wasn't quite 1/2" but it made me nervous. Everything has been fine though so i guess its ok. Thats with a vig and a TCI flexplate.

DanZ28

iTrader: (5)

Are you saying it was almost a 1/2"? That would scare me too.

FLT

iTrader: (1)

If you have a 1/2" there is something seriously not right with your setup. I would double check it before you rip the pump gears out of the pump. Vince

it wasnt a 1/2". But looking at it from under the car it looked like alot, turned out to be fine. I think i measured it to be about 3/16", maybe a tad bit more. I was expecting alot less though. In hindsight, if the converter sagged at all it would have made the gap appear and even measure bigger than it actually was.
