Bowler 200-4R Lock-Up Control Module

Complete 200-4R lock-up control kit with automatic 4th-gear activation, internal harness with solenoid and pass-through connector, gasket, filter, and optional brake switch

SKU: 5102000

The Bowler Performance 200-4R Lock-Up Control Module provides smooth, predictable, automatic torque converter lock-up without vacuum switches, extra boxes, or complicated wiring. Designed specifically for the 200-4R, this module engages lock-up 8–10 seconds after 4th gear, allowing the engine to gain RPM before locking in. This eliminates early bogging, chugging at cruise, and drivability issues common with stock-style lock-up setups.

The module features an integrated GM 4-pin connector and epoxy-coated electronics for long-term heat and vibration protection. Installation is simple, clean, and requires only a fused 12V ignition feed.

Perfect for hot rods, restomods, cruisers, and performance builds running a 200-4R transmission.
