i installed a transgo HD kit in my 04 tahoe today along with the sonax 4th gear servo and corvette 2nd

i used all the springs that came in the kit except the high rev springs, used 2 acumulator spacer washers, drilled everything for a "firm shift" not the all out race shift, and used no spacers in the servo pack, using the vette servo and sonnax made the servo pin play just about right

i road tested it for about 15 miles, no codes, no slippage, but the 2-3 shift is a little soft

1-2 is nice and firm and the 2-3 shift almost feels stock.

is this due to torque management- or did anyone else have this concern and figure it out? thanks

 

pretty sure that's normal, i know with only a vette servo and some tuning, my 1-2 is very firm and 2-3 is fairly stock feeling...except for the quickness of the shift

i'm sure others will chime in..

 

but i did install the sunax 4th gear servo as well

from what everyone else was saying i thought 2 washers in the accumulator would make it shift nice and hard

 

Are you still running all of your torque management?

 

Like everyone said before, probably normal. my 1-2 is very firm and 2-3 is alot softer.

 

yep full torque management untill thursday when i tune my truck

 

pull out some of that tm and it will kick

 

the 1-2 shift is crazy, i think i should pull a washer out, it snaps your head back at WOT

oh well ill update everyone thursday when i pull the TM out

thanks for the help
