Transmission Kickdown Detent Cable Compatible with GM Chevy TH350 TH250 1969-86

Universal Transmission Detent (Kickdown) Cable — Compatible with GM TH350, TH350C, TH250, TH250C (1969–1986)

Restore proper passing gear and factory shift timing in your Turbo 350 or Turbo 250 automatic. This adjustable universal detent cable connects your throttle linkage to the transmission's detent valve, telling the transmission when to hold a gear and when to kick down under hard throttle.

Symptoms of a Worn or Failed Detent Cable:

• No kickdown into passing gear at wide open throttle
• Late upshifts, or no 2-3 upshift until very high RPM
• Early, soft upshifts right after takeoff
• Frayed, kinked, or seized cable that will not retract
• Erratic shift timing after a carburetor or engine swap

Product Details:

• Adjustable telescoping outer conduit fits a wide range of engine and carb configurations
• Snap-in transmission end with locking adjustment tab at the carburetor bracket
• Ideal for stock replacement, SBC/BBC swaps, and street rod builds
• IMPORTANT: For carburetor/bracket-mounted setups only. Does NOT fit early firewall or gas pedal-mounted detent cable applications (common on some 1969–1972 Oldsmobile models)
• Verify your transmission uses the snap-in style cable end before purchase; some early units used an S-hook wire connection at the transmission
