Lot BW4302: 1970 Dodge Challenger

The 1970 Dodge Challenger came with several transmission options, each with their own common issues:

A-833 4-Speed Manual (Factory):

• Second gear synchronizer failure - grinding when shifting into 2nd gear
• Popping out of second gear due to worn dog teeth on the gear
• Broken shift fork ears, especially on the 2nd gear fork
• Input shaft bearing wear causing wobble
• Leaks from worn seals and gaskets

TorqueFlite 727 Automatic (Factory):

• Delayed engagement when cold (taking 10+ seconds to go into gear)
• Slipping in 3rd gear, especially during the shift
• Downshifting issues, particularly failure to downshift properly
• Chronic fluid leaks from the pan area
• Governor problems causing shift timing issues

G-Force 4-Speed (Racing - like in this listing): Since this specific Challenger has been converted to racing use with a G-Force 4-speed, the common issues are different:

• Gear spreading under high horsepower loads (though newer G101A models have center bearing support to address this)
• No synchronizers means rough shifting at low speeds
• Higher noise levels due to reduced helix angle on gears
• Requires speed-matching or double-clutching for smooth shifts

The good news is that the A-833 was generally very durable, and most issues develop over time or with hard use. For a race application like this Challenger, many of the street-car issues are eliminated, but you get the race-specific challenges instead.

Would you like me to help you find similar Challengers with different transmissions, or do you have questions about maintaining any of these transmissions?
