Things have been a little slow in this section so post them up . What transmission are you running or what transmission do you wish you where running for the 1/8 or 1/4.

 

RPM built 4L60 stage 5.

I love having the extra gear of the 4 speed. Not to mention a much better 1st gear vs a TH350 or TH400 with out the extra weight.

Here are the specs.
Media blast transmission case
RPM sleeved input drum
RPM 3-4 clutch pack
RPM reinforced sunshell with collar and bearing
Heavy Duty double caged 29 element sprag
4L65E low roller clutch
Billet 4th gear servo
Transgo HD-2 shift kit
Corvette Servo
Wide 2-4 band
Updated aluminum accumulator piston
Bushing kit
new shift solenoids
new wiring harness
new GM valve body spacer plate
GM 5 pinion planetary gearsets - front and rear

 

when i get my 307 built ill either run a rebuilt TH350..or a rebuilt T-5..good thing bout the 307 is theres not enough torque to break it , so i can get away with running a 10 bolt too...

 

700r4 here...

 

^yep.

700r4, the blacksheep tranny of the 4th gens. :P

 

eh 700r4=4l60/e

 

im runnin a 6 speed just finished upgrading it.
new sencry 1-2 3-4
carbon fiber blocker rings
steal 3-4 shift fork
bronze fork pads1-2 3-4
billet 3-4 keys

should hold good while that takes a beating ill probably pick up a spare and build that to viper spec. if i get tired of rowin the gears ill pic up a manual valve body th400 with a t-brake and big stall.

 

4T80E

Allison 1000 5-speed

700R4

i changed my mind. that one i said ill build to viper spec ill build a faceplated t56. by that time the car should be haulin some major a$$
