Soft Third Gear Shift ?

I just installed a Transgo HD2 Reprograming Kit in my 4l60e transmition.
The first to second shift is nice and firm but the second to third shift is kinda soft. Third to overdrive and the lockup shift seems firmer than second to third.
Is there anything I can do to firm up my second to third shift ?

A different 2nd gear servo on the band. A vette style servo is commonly used. this will tighten up the 2-3 slightly

Remove the capsul & check ball assembly from the servo area... replace with a cup type plug driven into the hole to block the passage into the inner case

Was the trans rebuilt prior or during this installation of the TG kit?

OK... make, model, year, mileage of the vehicle? Mileage on the tranny the same as the vehicle?

A shift kit can not fix a worn / high mileage tranny.

The 3-4 clutch pack of these trannys have been a problem since the 7004r was introduced. This is the shift you complain about (2-3 shift).

The 2-3 feed hole can be opened to .110 maximum without any side effects, as long as the Corvette servo is used. To go any bigger requires other changes, so .110 is max. on the 2-3 feed. This will firm up third a little more than the .093 2-3 feed as suggested. Do not remove the checkball capsule that is behind the servo as suggested, as this can have other side effects. TransGo will tell you the same thing on this. As stated earlier, the transmission must be in good shape as this kit does not fix a worn out unit.

soft third gear

I like opening the 2-3 feed to .110, that will help, it's good the servo made a difference, maybe save you the trouble of pulling the valve body.

Now that the input drums have an air bleed cup plug, to bleed off residual fluid [ from 3-4 ], removing the checkball capsule, in my opinion, is a good measure of insurance. Too many 2-4 bands and reverse input drums, get ruined when the ball does not seat in the capsule correctly.

The capsule is considered the vent for a crossleak [ from the sealing ring closest to the drum ], Steve Younger, [Gill's son ], has written some great info regarding this crossleak.

Being hard headed, like I am, and because I've seen what this checkball capsule will do to a 700, or 4L60E, I've been removing the capsule, and blocking off the subsequent hole for over 15 years now.

I am aware of some of the general consciences involving this checkball capsule, but for me, this has worked out fine.

I've seen no side affects in many years with this mod...
