How to tell if stall converter is seated
 
1 Attachment(s)
This is my first time doing a transmission swap by myself. i removed my 700r4transmission with a breeze. Then i put my rebuilt th400 up bolted it to the block. A friend of mines ask me if i seated the converter correctly now he has me freaked out. I remeber hearing a click but i dont remeber how many i heard. so now im not sure if its seated all the way. The converter turns freely.

I know this is hard to tell if it is accurate from a picture. but before i unbolt the transmission. this is how it looks under there. Also i measured and the converter is half a inch from the flex plate. what do you guys think should i be on the safe side and unbolt the transmission or leave it how it is.
THanks for reading

If the converter spins freely as the trans is bolted up , you are OK.

Your photo does not look like a 1/2 clearance. Looks like less.

1/2 inch is too much pull out from the trans to the flywheel. Should be around 1/8 inch

yeah your right i couldent read the measurements on the tape measure because of the metal tap so i rounded up to the closet number i coulde read which was a 1/2 inch. what has me worried is when i turn the converter the splines on the back on the transmission dosent turn. every time i ever delt with a transmission when i turn the converter the splines on the back turn with it. but also this is a 10in tci street converter and my first time experienceing with a stall converter, i dont know if that has something to do with it

What is a "stall" converter? They all stall at some point. :confused:

If the transmission bolts up to the engine and you still have clearance between the flexplate and the converter, you are good, don't worry about it.

thanks thats all i wanted to hear. my friend keeps telling me im going to break the front pump. but i think it is right. i have a peace of mind about it now

i have another question guys do i use a spacer between the converter and flexplate. or do i pull the conventer to the flexplate and bolt the bolts

T-bucket23 07-17-2012 02:16 PM

generally it is just bolted in. The clearance is usually no more than 1/4" from what I have seen. More than that and I think spacers are in order as the converter lugs may get pulled out of the transmission to far.

This "friend" probably wrecked one or more with his wrench twisting prowess. As others have stated, you sound like you are doing fine. I would have dumped a quart or two of fluid in the converter before I slipped it on the input shaft. Also rubbed some fluid on the converter hub to get it passed the input seal. You probably didn't do that either but don't worry about it. If he really is your friend he would be over with you at least handing you tools.

Keep us posted on your progress!

IMO, Lubricating the convertor hub/seal is vital!
If you start that engine up on a dry rubber seal ... it's going to burn up.

Just a little vaseline or assembly lube is all you need.
