Does anyone out there know if a C4 AT can be put in a 90 SC originally equipped with an AOD? Is this recommended? Not recommended? I am told the C4 is a much stronger tranny. Any suggestions?

Any problem will Go Away, if you throw enough money at it!!!!!!

The C4 conversion will be expensive. Yes, it's a stronger (stock) tranny, but lacks OD. Don't forget all the custom bits & pieces you have to fabricate.

The AOD has issues with a weak (stock) inner input shaft. Plenty of people have snapped the inner shaft. Lentech can build you an AOD that will take more power than any SC can make. There again, they are expensive.

If it were me, I'd have the AOD built. If you've ever ridden in a car with a Lentech AOD, you'd know why!!!!!!!!! With the Lentech AOD you still have the OD for cruisin' but have much stronger equipment for racing or Illegal Stoplight Competitions!!!!!
