Transmission & Bellhousing Kit TH350 to Chyev Holden & LS

Designed for the extreme high performance street or all out race car, our Full Manual Competition Transmissions will give you consistent shifts as well as complete control over shift points. This version (Part# 312000) has a forward shift pattern and requires no vacuum hookups or kickdown linkage. This means there are no external linkages to be purchased, which saves some expense. The increased line pressure provides a harder, quicker shift and eliminates the lag time between shifts produced by automatic shift transmissions.

• Extreme performance clutches and nitrided steel plates for enhanced performance
• High-performance power bands provide greater torque capacity and more positive shifts and band apply
• Hardened sprag races increases durability & strength
• Improved lubrication system increases fluid sent to planetaries and internals
• Able to handle up to 750 HP, depending on application

Part# 312000 Specifics:

• 6" Tailshaft

Transmissions for maximum performance, then dyno tests and pressure tests them. So you can concentrate on winning the race!
