overdrive

Does anyone have a Manual for a "T & H Products, Inc." "Todd Toyota Overdrive" unit? I searched and found a thread from 2011 where JohnnyC said he was thinking about rebuilding one. I purchased one with a drivetrain but the seller forgot to put the Owners Manual on the pallet. They mailed it...

I have a 1971 Toyota FJ40 that originally had a 3 on the tree. I am going to convert it to a 4 on the floor. At the same time I purchased the 1978 2F engine I also got with it a 4 speed transmission + transfer case and Todd Toyota Overdrive unit. Question: Can I run the Todd Toyota Overdrive...

Hi all Can someone please help me understand the difference between the O/D button and the PWR button? I see online they both increase the revs before shifting gears. Why have the two options? Is the PWR just more responsive? Thanks

On my automatic Landcruiser and other automatic transmission cars, I usually drive with OD on (meaning OD OFF light not showing). Reason is that I do not encounter extremely steep hills. The car simply moves effortlessly up and down hills. I do the above based on my understanding of overdrive...

I had to have my heater core cleaned out because it was clogged. After everything was all put back together my overdrive light is flashing. When I turn overdrive off it doesn't flash. From my understanding that's the shift solenoids but I replaced them in 2022 and had the transmission rebuilt...

Have any of you guys taken apart the O/D switch on the shifter handle? Am I missing any pieces? My O/D button fails to stay latched when pressed causing my O/D OFF light to be on all the time.

I am wanting a 5531-B, 5531-C, 5831-D, or maybe a 6231-A Spicer Auxiliary Transmission with at least yokes, preferably with driveshafts to, and shifter. I need a model without a power tower. Also if anyone has a Watson Model 41 or 42 I would be interested in that as well. I need a 3 speed...

On the drive to Silverton, in our old 99 LX, I noticed an unexpected behavior when disabling overdrive... Overdrive Off switch illuminates the light on the dash as expected. (The light is "on" with the switch in the "out" position. The light is "off" with the switch in the "in" position.)...

Hey guys, A brief intro as this is my first post; I recently bought an ‘04 100 series after quite the extensive search. She’s still just a baby at 120,xxx miles and since purchasing her I’ve dumped thousands into baselining her and getting preventative maintenance under control - timing belt...

Hi everyone. My 1st post here. I need your help. I have a 82 LJ78 for the last 4 years. I got tired of the underpowered 2LTE engine and swapped it with a 1KZTE but kept the transmission from old engine. Now, it is giving me troubles (tranny has been rebuilt once as it was slipping in all gears...

Hi everyone, I've been doing extensive research on how to tow with the LX470, and have read a number of accounts to TURN OFF overdrive while towing, even on the highway. But I can't find the button to press for the life of me... Could someone please kindly help. Or is it not available on the...

Hi everyone - I'm trying to rectify some of the terrible deeds that were done to the wiring of my 62 by some previous owner. When I pulled the O/D switch, I found that none of the wires were attached to anything (strangely, the O/D still seems to kick in at around 50 mph). I have looked at...

Hello fellow 100 series owners, Had my lc100 ‘01 for a little over a year now. Put 20k on it since purchase. Put a lot of monet in it fixing it up. I’m nearing a cross roads in what to do. Ever since I’ve owned it, I notice the MBC shakes briefly occasionally. I assume it’s the factory...
