will this help with my 4t60 tranny?
If I put the modulator valve on (part #md 28 ) will that help with my trnny not shifting to OD until 50 to 60 mph? the tranny shfts great in all other gears.

With almost nothing for load on the engine the trans should shift at 50 mph..

so this is normal?
It seems like it is taking longer than it should to get to that last shift, it is usually at 3500 to 4000 rpms. I already have a tranny cooler installed,would this still be a good idea?

I forget how much control the Vacume modulator has as far as shift timming is concerned... The first thing I would tell you to do is make sure the TV ot Throttle Valve Cable is adjusted properly

From articles I have seen on the 4T60, the modulator controls the shift feel and the TV cable controls the shift point. It is apparently a little different from some other transmissions in this regard.

Hallelujah!
My darling wife gave me another night to work on the bonne, and man did I take advantage! I put in the new modulator and adjusted the tv cable, made 2 slight adjustments on the modulator to get the tranny shifting the way I like it and she runs like new. Shifts at 3000 to 4000 rpm depending on the terrain and cruisin at 60 and 2800 to 3000 rpm. I hope all that sounds like good #*, because she runs and shifts great! I'm going to bed now, its 6am. Ck your replies later!

2800-3000 at 60 almost seems like you are not getting into Overdrive

ok, so what now?
what kind of adjustment needs to be made, the modulator or the cable? :?the last adjustment I made was on the modulator and that brought things to this pt. Should I loosen it some more?
