I was under the impression that the passing gear or kickdown was electric on th400's.

I'm running a th 400 out of a commando and its electric. I don't even have it hooked up. It will kick down without it

TH400 kickdown is electronic.

Kickdown switch is mounted to the firewall and activated by the accelerator pedal arm.

I've heard it's hard on the transmission that way. No personal knowledge, just what I have read in my TH400 research.

Mine originally wasn't working due to a burned up wire hitting the exhaust. It made a big difference once it was working properly. It would kick down without it hooked up, but is night and day with it actually working.

sorry if i wasn't clear in i was aware the kick-down is electronic that's why i said i found the lokar kick-down but it mounts in the same spot as the shifter cable on transmission pan.

i thought about doing this also but heard and read on other threads that its really rough on tranny and can blow out the seals after while.

i also found the B&M kit but seems it only works if had TH350 or 700r4 before.

I haven't been too concerned with it. It's a very rare occasion that I ask mine to kick down. It sees very little highway and no interstate driving but I reckon that's a perk of living in the country, you don't usually have to hit a highway to get where you're going.

I don't have a clue why they say it mounts to the tranny pan, maybe so it's out of sight. The Locar still needs hooked up the the carb , to activate the kick down. And needs 12 volts postive to operate.

The only thing that gets hooked to the tranny is 1 wire. 12 volts + from whatever kickdown you use.

B&m makes a pull style switch for the th400 that mounts on the throttle linkage.

I assume you're runnig a gm motor, if so, get a cable bracket with an adjustable kickdown mount if you don't already have one. Oreilys has them on the wall and they are only about 10 $.

Here's how it will look in the mount. Its a pretty straight forward procedure. Then all you do is run a wire to a 12volt switched source then run a wire to the kickdown solenoid. Adjust the bracket to what throttle percentage you want tge kickdown to come in at. I usually do it a lil less than 3\4.

The OP is using a AMC 304, you idea would still work.

OP, I have a OEM gas pedal kick down. It's yours for the cost of shipping! I don't know if it works, if your interested, I'll check the switch for proper operation.
Let me know.

i saw that B&M one but was unsure because the descriptions i saw said it would work only if you had previous TH350 or 700R4 then you could use the old hookup for it so was unsure.

Any type of momentary switch will work. I've seen people use mirco switches, the same used in nitrous systems. But the bm will work. Its universal
