Is it adjustable?

Thanks,

No. But they aren't that expensive. What is the problem with the tranny?

I'd just like it to shift at a lower RPM. It's an L-48 so it kinda dies after 4000. The guy at Discount Auto Parts thinks that his is adjustable. It's just the stock replacement though for 10.99. So I was just wondering.

I don't know if it was stock, but the modulator I took out of my TH350 was NOT adjustable. The adjustable one has a screw in the smaller nipple (not the bigger one that goes into the trans).

You may want to check the rubber hoses at the modulator and the intake manifold. Mine had a hard line connected at the modulator end and the intake end with rubber hoses. The one at the intake was shot. If you're sucking air in there it'd probably affect the shift point.

Also, I'm not sue of it's function, but, page 6 of my B&M kit instructions ( http://users.erols.com/jerryp58/corvette/BNM6.jpg ), talked about removing the accumulator spring. You should've skipped that step for the street/strip version, but FWIW, my accumulator spring was broken in two different places. Like I said, I don't know what the accumulator does, but if the modulator doesn't help things, you may want to look at that spring.
