Inliners International Forums General Discussion Vortec 4200 4200 parts - whats needed to help folks use this

Mike,

Any 4L60E that came behind a LS series engine will work as long as you change the bellhousing. The bolts holding the bellhousing are IP50 head DO NOT ATTEMPT TO USE A TORX BIT, you will bust the bit and/or strip the head of the bolts in the process. Either take the trans to a transmission shop and ask them to swap the bellhousing or by the IP50 bit from snap-on. These bolts are hard - even 100% carbide bits have a hard time drilling them out. Trust me you don't want to go there.
