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. Key Features Automatic converter lock-up 8–10 seconds after 4th gear No vacuum switch required — works with carb, EFI, or boosted engines No bulky external box — GM 4-prong connector integrated into the board Epoxy-coated for weather resistance and durability Simple one-wire hookup (2-amp fused 12V ignition) Reduces chugging, surging, and premature lock-up bog Improves throttle response and highway drivability Full kit—no extra parts needed What’s Included Lock-Up Control Module New Internal Wiring Harness with Lock-Up Solenoid Solenoid mounting studs Case pass-through connector Pressure Switch Pan Gasket New Transmission Filter Brake Switch Function The included brake switch improves lock-up control by allowing the driver to tap the brake and instantly unlock the converter.
