I know my stock trans likely won't survive much longer as I am shooting for mid 10's in the 1/4 this year and truly should be able to reach that goal. Question: If I wanted to buy a new or a used 700R4 that has been beefed up, what do I get so that it bolts right in to a '89 vette? Is it only the C4 specific 700R4's that will bolt in because of the tailshaft? I really don't want to get into swapping my stock tailshaft onto a new or a used trans.
Anyone have a beefed up 700R4 that will bolt right into my car, will work with my converter (that works with my stock trans and is a lock-up converter), and has an automatic valvebody that they are interested in selling?
Just thought I'd throw it out there.
Corvette has a unique case, valve body and tailhousing. A typical 700 can be adapted, but the builder must know what he is doing to properly achieve it.
If you ask 10 builders what they recommend for a mid 10 second 700r4, 7 would say it can't be done, and the remaining 3 will have specific recipes for getting it built right. All 3 will likely disagree on the build content.
When you find the guy willing to help, I recommend discussing: max rpm you will spin converter that will be used rear gearing hp and torque you will be tossing at it Power adder used
With the above info, the builder will cater to your needs. When I was b uilding them, that was where I hung my hat. Custom built to suit the car, not an off the shelf, 1 size fits all unit.
Sorry I was not more specific, but the best I can do for now.
