700r-4 lock up

My converter currently locks up at 43 MPH. That's a bit low with 3.08's. Is there a different pressure switch that can be installed to make lock up happen at 55 MPH ? I have played with the TV cable and all that does is make it rev way up before shifting.

This trans has everything in it, beast,kevlar bands,koleen steels, transgo shift kit.

thanks guys

Mike

I like to install a 4tgh gear only lock up kit in them. Cheap, simple to do and makes it a bit nicer to drive. 1 simple option. Reprogramming the chip is another. I prefer the lock up kit for 4th gear though.
