4l60e vs. 700r4 on carb'd LS1???
Its time to settle on a transmission for my carb'd LS1 thats goin in my '72 C20 Suburban. I already have the bowed flex plate with the wallowed out holes, required Tq converter, and the adapter for the crank snout. My question is, for my application, is it worth going with the 4l60e and dealing with the cost associated with the stand alone controller that will require a throttle position sensor not to mention either the $300 adapter to run my old school mechanical speedometer, or swapping my gages to something more modern.
As far as Ive read, the two transmissions are identical outside of the computer, so whats the benefit of one over the other. This is a daily driver so Im looking for reliability and simplicity, not concerned about horse power or track times.
Lastly, if I do go with the 700r4, what else do I need to get it to work? My current set up is a th350 with column shift.
Thanks for the help!

90-92s are the same as the 4l60e, they just aren't electronic. I have run a 700r4 behind a mild v8 for years with no trouble. You do have to have the cable adjusted right, which is why most people ruin them and call them junk, lol

Fair enough...I've got a rebuilt 96-98 4L60e sitting in the garage, I was just looking at the mounting expense of the TCI controller, TPS sensor, and then some sort of speedo adapter and thought the 700R4 might be the cheaper and simpler way to go....after selling the 4L60e

It's no problem ask questions that's what a forum is all about. Well it connects to the transmissions main plug then you connect two wires one goes to ignition power. The other to a ground switch when ever your in 3rd and 4th. You ground it and it locks the converter. When you have to manually shift it. Start in 1st. When you need it shift to 2nd and so on. I used it in my jeep for 2 years now works great.
