ok, this morning I called my local custom trans shop and asked how much it cost to have my 60e built and how much would it cost to have a 80e installed, this guy told me about $3,500 to $4,500 my 60e built to hold 350hp to the wheels not including labor and $12,000 to have a 80e semi built and installed,then he said that those trannys off the internet wont last me 100 miles, when he said this i laughed and hung up.

he also said $350 total for him to just swap mine for a new built 60e that i would provide, which i guess is reasonable?

so i'm asking anyone who has experience, what should i do??

..and also all i have is a 06 5.3 with a tune, shift kit, servo and magnaflow turndown
