I bought a Yank converter to go with my new TH350 from Rossler. I'm putting the converter into the transmission right now as I'm getting ready to install the transmission. Everything I've read on this forum and on Yank's pamphlet that comes with the converter says you need to have 1.125" from the bell housing to the converter pads, but every time I get the converter seated all the way I am only getting 1" from the bell housing to the converter pads. I've pushed and spun and I cannot get it to seat any further to get the extra .125". I even checked with a trick of mine to see if the converter was seated all the way. As seen in the picture below, I took some all purpose grease and placed it on the converter where the notches are on the end of the shaft. I seated the converter all the way, and then pulled it out. There was clearly grease left behind on the male part of the pump inside the transmission, telling me these two parts mated together, but I still only measured one inch!! If these two parts mate together doesn't this mean the torque converter has been pressed in all the way?
Any advice? Do I have the wrong idea here? I'm just worried I wont get proper pump to converter contact.

Try mounting the trans up to the engine with the verter in and see if it has to be pulled out a little to mount up to the tabs.If it is too tight then you have a problem,if it pulls out an 1/8 -3/16 to bolt up you should be ok,as it needs to come out of the pump a little so that it does not bind up.
