Spitballin' here. Should have paid more attention when others asked basically the same question. And of course, I don't seem to be able to use the right search words. What trans uses a simple on-off button for the OD and no electronics? A500 or 518? And would it live behind a 360 in a pick-up doing moderate towing? Thanks, Tim

Thanks, the '88-'95 unit is the one I was thinking of. Do you have to activate the OD very time or can you simply leave the switch in the "ON" postion?

Tim If you leave it on the transmission will shift immediately into fourth gear as soon as it shifts into third. It will still down shift on its own with speed, but will not down shift with the kick down. Leaving it on effectively makes it a three speed with a non-functioning kick down. I don't think it does anything bad to the transmission itself. This is only for OD though. You cannot leave lock-up on if you have a model that does have it - that will do damage. Honestly though, a pressure switch and vacuum switch is all that you need to automate fourth gear. Add one more pressure for lock-up. It's not complicated at all.

Thanks. Food for thought. Just thinking of a possible future project and how to do it. Tim

I'm actively looking into the 4l65 swap for my Gen3 Cuda because it's a small case design with OD and lockup. I don't know enough about it quite honestly to "sell" the idea to anyone else but it may be something to look into for you.
Because it's a GM trans, parts seem to be available, affordable, and you can buy supporting parts and pieces at Jegs/Summit

I put a 2002 A500 in my Charger behind a 1995 5.9 Magnum. I mounted two switches on the console. With 3.55 gears I did not need to switch them on until I hit the highway. It never bothered me

Because it's a GM trans, parts seem to be available, affordable, and you can buy supporting parts and pieces at Jegs/Summit I can see this having upsides if the OP was inquiring about an OD automatic behind a big block, but seeing as how Mopar made transmissions that bolt right up to his small block it probably isn't worth it. When I stuck a 518 in my Fifth Ave behind a 360 I did it for under $1k. The aftermarket support isn't lacking either. Then again, if it doesn't require surgery to make it fit then toss everything I said right out the window.

I have an a500 behind the turbocharged 383 in my 70 Fury. Psi switches for OD @ 45pmh and lockup @60mph, 3.91's and 28" tires, I don't like to lug it around. In the C body no tunnel work, just a custom mount.

Thanks for all the input. I just scored a Dakota QC 2wd, 5 spd. with no engine for a song. Durango is a little ragged after the 2 not-my-fault accidents & really miss having a truck. Engine & many of the parts from the Durango will live on in the Dakota. I think it will be a fun little ride. Reason I asked about a simple OD auto swap is if I get tired of rowing a stick. I'm not getting any younger & since we moved back closer to Atlanta traffic is a bear. Thanks again. Tim

I've been to Atlanta during rush hour many times. Let's just say I would rather slam my male member in a sliding glass door than drive through that everyday.
