Making the 200-4R "bullet-proof"

...or at least pretty strong... :)

The 700 is a stronger trans, a disadvantage is slightly higher ratios for all gears (except 3rd of course) I say "disadvantage" for those of us who want to get a little more gas mileage out of it. For full race, the 700 is an easy choice.

Aftermarket 700's can be found for around $1550.

Read: trans ratios

The 350's and 400's are good trannys as well but these SS's love the 4th gear.

For more good info on building up the 200's, talk to a GN owner...

TH200-4R build-up parts list:

-Hardened stator support
-10 vane pump
-Hardened chrome pump rings 
 (stock are cast rings and break, another cause of failure), 
-The newest re-designed pressure regulator valve 
 (it's been re-designed about 4 times so far)
-Opening up the front pump seal drainback hole to at least 5/16" to keep 
 from blowing the front seal out. 
-The Kevlar band is a VERY good band so long as the band clearance is not
 too tight. 
-Change the servo apply pin to a 3 ring or 0 ring (longest) pin to apply 
 the band around the direct drum. This along with a GN servo cover, piston 
 and 3rd accumulator piston. 
-Add the extra clutches to the direct (3rd gear) and overdrive(4th) clutches 
 as well as the hardened forward clutch housing shaft
-B&M Stage II shift kit (Transpak)

Proven neck snapping shifts good to roughly 450HP. (estimated)

A higher stall converter along with a nice strong limited-slip rear is also recommended. Good u-joints are a must. Traction bars are a plus. :)
