New Converter Trouble

Over the winter I purchased a new converter to replace what I thought was a broken sprag. I decided on a ~5200 stall from Transmission Specialties Inc without a sprag. I ran the new converter for the first race of the year and noticed zero difference in any incremental times. I got home and tore the trans apart and replaced the intermediate band, which was pretty much shot, added a R-Code TCI servo and a Sonnax F Code shift lever. I buttoned every thing back up and the truck will not move and the front pump will not pump. Last night I pulled the trans again and the gear in the front pump was chewed up and stripped out from the converter stout. I replaced the gear, measured everything and put the trans back in tonight. The new converter is the same height as the old one. Again the trans did the same thing. The truck will move a little upon start up and then nothing. I am assuming the gear stripped out again and it acts like the snout is not fully engaged in the pump. Any thoughts.

little over 1/2". It is probably too much but I ran it for a weekend and it worked fine.

So the $900 converter Transmission Specialties sent me needs a longer snout.

shim the converter back to get the correct distance and clearances....

no, there are just a lot of variations involved with different setups so you have to measure and use shims if needed. Not all flexplates and bellhousings and everything else involved are the same and converter companies have to build the converters to fit every variation.

good luck.
