1G versus 2G torque converters

[jlsperok]

What are the differences between a 1G and a 2G torque converter? FWD perferably.

I completed a 6-bolt swap in my '97 GS-T automatic, and am now having a problem with the 2G starter engaging correctly in the converter. The trans I bought was rebuilt with a newly rebuilt (never used in that trans) converter. I put the 6-bolt in at the same time as the new tranny, so I am trying to pinpoint my problem. I know about the spacing for this swap, etc....

The converter has a few 'chipped' teeth on it, and am wondering if I should just replace this converter, or if it is even the correct one.

I just want to make sure that I wasn't given a 1G converter with the tranny on accident. Are there obvious differences, such as the diameter of the ring? I know mine has lock-up as well, just looking for visual differences. Any info would help me greatly!

Thanks,

1G and 2G converters are a completely different overall height.

The only correct way to do the 7 bolt to 6 bolt swap is with an adapter plate, the correct flexplate and the correct bushing in the back of the crank. Doing it any other way will cause damage to the transmission, torque converter and starter.

Yes, I have the CAD diagrams and everything about how to do the auto swap. I have constructed the spacer out of 1/4" aluminum, hvae a 4-eared flexplate ( X ) for a 6-bolt and have the bushing as well. The car runs great, just not sure on the starter issue.

I am guessing that the messed up teeth on this converter are causing the problems, and I will have to go with another converter that has a perfect ring. It's not like the ring is tore up, just a few teeth have some wear, but that might be enough.

I took the converter to a guy that builds race converters here (non DSM specific), and he said it looked fine and he wouldn't hesitate to put it back in the car if it was his, so I did. Maybe the DSM is just that picky.

Here is a link to my website that has all the pics so far of the swap: www.sperko.net/eclipse.asp

Thanks for the info though, sounds like if I had the wrong one, it would be obvious.
