Thread: Torque converter

Tweet

Installing a TH400. I want to make absolutely sure I have the torque converter properly engaged on the tail shaft to avoid a disaster. I have specs from the internet stating after 3 distinct clicks the torque converter should be all the way into the transmission and should measure as follows "from bellhousing to converter pads = 1.187" +/- .050". I cannot find any info ANYWHERE that mentions the term "converter pads" (so typical of instructions). Is it the housing face of the converter, the flat spot the 3 nuts are welded to, the pilot nose, what?

Thanks for your help

The best advice you can take is to mount the converter to the shaft..........push it in and keep turning it till it seats. You will be able to feel the converter seat as you turn and push.

I think what "they" are referring to in the term "convertor pads" is the mounting nuts. It sounds like "they" want you to use a straight edge and measure back to the mounting point(s) to see if there is enough clearance to mount the tranny. That would be my thought FWIW..

Sometimes the first drop is so smooth you don't feel it. So, just rotate it and push in, you'll feel it drop. You'll know sure it is fully seated when you mate up the motor to the trans: you'll have to pull the converter slightly forward to meet the flexplate.
