Product Details

The BD Diesel 1600411 On/Off Lockup Kit is a transmission upgrade designed to improve shift quality and torque converter performance in 1999-2003 Ford 7.3L Power Stroke trucks equipped with the 4R100 automatic transmission. This internal transmission modification replaces the factory PWM (pulse width modulated) valve assembly with a new On/Off valve assembly that provides immediate, positive torque converter lockup engagement.

Key Features:

  • Converts soft, gradual PWM lockup to quick, crisp On/Off lockup operation
  • Replaces OEM PWM valve assembly in transmission pump
  • Drop-in valve design requires no special tooling or machining
  • Extends torque converter service life by eliminating slippage
  • Reduces transmission heat during towing and heavy load operation
  • Designed to work in conjunction with BD Tugger Shift Kit (part #1600410)

Installation Notes:

  • Requires complete transmission removal for internal component installation
  • Professional installation by an experienced transmission technician is strongly recommended
  • Should be installed as part of a comprehensive transmission rebuild or upgrade

This lockup kit is ideal for diesel truck owners who tow regularly, haul heavy loads, or want firmer transmission behavior. By eliminating the gradual engagement of the stock PWM system, the On/Off lockup provides better control over transmission temperatures and reduces the wear associated with converter slippage. The kit includes all necessary valve components for a complete conversion.

Lowest price and S&H around! Prompt responses! Will def buy from again!

I looked around for few months on where to go to purchase JBA headers for my 01 Tundra. I came across Autoplicity and their prices were untouchable. I even called to speak with a sales representative and he gave me a discount code for my purchase. I would highly recommend doing business and plan on doing more business with them.

Best price I could find on line, shipped really fast. With how low the price is I was worried but everything came fast and it was the correct parts. This place really keeps the cost of racing down.

I received my ARP head studs as described and on time with zero problems, and cheaper than anywhere else.Will use again!!!

Very easy. I hope shipping is the same.
