I got all the parts i could from finish line trans for my tranny when i built it 12,000km ago. All the trans go goodies, everything that was available, plus a yank 2600 and it it all put together professionally. Well 2-3 is slipping at wot and same into overdrive at mid throttle!

I drive the truck only on ncie days and i drive the **** outta it...realized i shoulda jsut got a FLT build unit to begin with...but live and learn.

Also, instead of running a factory t-56 id rather put a big beefier unit in as i plan running boost...any online reccomendations for buying heavier t-56's?

thanks guys

 

i know flt makes heavy duty T56s and also D@D motorsports but you should also look into a T56 outta a GTO cause i hear there better for our heavy trucks cause the gearing is lower then you would'nt have to run low gears in the rear end to even out the the higher gearing in one outta a camaro or a TA or even better find one outta a viper i know someone on hear put a trans outta a viper in there truck but they had to relocate the shifter

 

Im already running 4.10's so Id be safe with a fbody t56

I see kiesler has brand new ones rated for 475/475..which is about exactly what numbers i will shoot for in the future

 

not sayin your wrong but id talk to turbogibbs as far as the gearing goes cause i know he's runing 5.13s and he has a f-body t-56 and 1truess is runing a t-56 and he's running 4.56s im pretty sure its got somthing to do with the tire size

 

hmmm..well maybe i'll look for that gto mm6...let em look into it..worst case i need more gear

 

I dont know that you would "have" to, but most guys gear it so that its running up around 2300 or more at 70. Which if you can run a lot of gear, why not.

 

Due to repetitive questioning on the gears, it is the same final drive as a F-body with 26" tires and 4.10 gears since my 20"ers are 32" tall. I'm doing 1900 rpm @ 70 mph on the highway. My 1st gear is 2.66, and a 4L60e is 3.06)

here you dude this is from turbogibbs
