Barn motor and tranny swap

[good2win22]

I'm not sure what we are measuring there but I would set the new converter and look inside. Count the splines in there. You need it to have 27 splines but I bet it has 30 splines. Just a hunch.

Let us know.

I guess we should have stabbed it on there while we were up there.

Rich, that measurement in the pics is from a straight edge across the front of the bell housing to the mounting lugs on the converter.

1 1/8" is correct...when installed and bolted up, there is normally about 1/8"-3/16" clearance between lugs and the flexplate as I recall.

It should click three times as it slides into the transmission-unless I am more senile that I admit to.

Did you measure/compare the nose lengths?

Also, sit the converter on a table on the pads...lay a straight edge across the nose and measure between the table and the straight edge.  Do the same for the D5 and compare the two measurements

I'm getting the three clicks.  There is no difference in nose length. 
the height of the converters measure the same. Approximately 5 3/4. The only measurement that is not same between the two converters is the internal depth.

I have not counted the splines. I will do that

Look in the trans to see that pump bushing. He had a converter in it so I doubt that I the prob.

 The 30 spline stuff is more common as the later 700r4 and 4l60e is 30 spline.
I know they stuck a 27 spline input down into the converter when I picked mine up from my guy . We should have had him do that.

Spline count is not the problem

Then id keep spinning it so it can drop onto the places it needs to. Maybe turn the output a bit as you try to seat it.

[good2win22]

I think I might have found something.  Measured the depth inside the converter where the first set of splines would bottom out against a lip. 1.475. Then took that measurement and put it up against the second set of splines as you can see in the pic.  The distance between the second set of splines to the front of the first set of splines is 1.525. That's almost a 1/16th. Maybe not enough to get the 1 1/8th that I'm looking for but what other dimensions are in question

Is it the top where it engages into the pump overall height of the converter is the same?

.
Over all height is same. Put some grease on the notches for Jake. Pics show the results. About an 1/8" from fully seating.


Went to measure the stock converter to compare dimensions from the above post and found that the stock converter has a countersink to allow the front set of splines sit further down. Jakes converter does not have this countersink

Maybe this will  offer some solution.

Thanks for the link Rich.  I'm headed back to Sanger in the morning and not leaving till we come up with a solution

Did you stand it on end and give it a whirl as suggested by david husek?

Yes sir. It didn't help

Went to Jake's this morning and spent about 3 hours there. We measured and measured and then cut open the converter. Stacked the converter pieces on the input shaft without the shell. That was pretty neat to see. Can't find anything amiss. Chucked up the billet bottom and cut off .100 off the mounting lugs. Put it back together with a different stator.  Welded, test fit it into the tranny and BAM! 1 1/8th from the bell housing. Pressure tested it and then threw on some paint.  Off to the house I go.  Get to the barn and mount up the tranny to the block and BAM! We got clearance.


So fortunate to have him take care of me like he did.  He mentioned that this was only the third converter that they have ever had problems with.  On a side note, I learned a lot today. 


Engine and tranny are in the car. Glad to have gotten the easy stuff out of the way!

Sweet!
