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.

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?

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.

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!

yea that does seem a little high, if i recall im lower than that at 60 and i have the gx3 :?

At 60 I would expect the RPM to be around 2K or slightly less.

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?
