65 Riv - TH400 - replacing kick down solenoid etc...

Recommended Posts

Hi all

 

I need to change my switch pitch/kick down connector terminal at the transmission...its spinning...and potentially the solenoid inside...

 

RE the solenoid - manual suggests i need to remove control valve body assembly/gov pipes (pg 5-109) before removing what's referred to as 'detent' solenoid...but rae these instructions refrring to a full tear down? Will it be possible to remove and replace solenoid without removing the valve body?

 

Also...manual refers to an 'electrical detent solenoid  (kick down) AND stator solenoid (switch pitch)' - is there an additional solenoid for the switch pitch somewhere? or does the one 'detent' solenoid control both functions? I think it does both - but thought i'd check...

 

Thanks in advance

On a 65, the terminals for both are in the one part.  They are positioned in the shape of a T so you can't plug the wires in wrong.

I’m thinking more of what happens on the inside of the pan - the solenoid. Does that ‘detent’ solenoid handle both switch pitch and kick down functions? Or is there a second solenoid somewhere inside transmission...

 

Cheers

Two wires, two soleniods.  In 64, the kickdown is handled by a solenoid, but the 64 transmission does not have a variable pitch torque converter - one wire, one solenoid.  I do not think that the "switch pitch" and the kickdown engage at the same instant.

Ed is correct - pitch control and kick-down are independent functions.  The 'kick-down' switch on the throttle linkage of a switch-pitch car likewise contains two sets of contacts.  High stall switchover occurs first, followed by kickdown to 2nd gear as your foot approaches the mat...

Indeed...but as per my original question will I need to remove valve body to get to the detent solenoid  and if there is a second solenoid where is it? maybe in the torque converter itself?...

 

thanks

used my initiative - wait for it, wait for it - took the pan off and had a look!

 

all questions answered

 

both solenoids clicking, so just the two prong connector to replace (spinning and leaking)

 

cheers
