This is good to know.Yeller wrote: ↑Tue Dec 27, 2022 3:51 pm If you weren’t after OD, 727 or T400. With overdrive in the mix 700r4 would be my pick hands down. No electronics and robust. No matter what trans you go with it needs a large cooler.
I have one pushing 380hp/380ftlb that has been living a hard life for 15 years and approximately 80,000 miles, with at least 1/2 of them off road. If it laid down today, it would get an overhaul and I’d smile about it.
Yeah, I'm aware they are the same. I just have only heard of the more recent 4L60e failures. Most likely, it's like everything else here in podunkville now and due to lack of preventative maintenance. There's a reason I don't buy anything mechanical from the junkyard or off of marketplace. It's complete junk by the time it's available at either place.Yeller wrote: ↑Tue Dec 27, 2022 7:08 pm The 700r4 and 4l60 are the same. The 4l60e is the same internally with electronic controls. 4l70e is an upgraded unit that the upgraded parts carry over to the previous units. The 4l70e can be purchased with the “hot cam” LS3 from GM Performance with a warranty so they are proven units. I’ve been around some thumping, stroked 500ci+ big block chevies with 700’s that are happy.
I believe they are referring to the electric controlled Converter and Overdrive. There are several kits to make this work the way you want. The easiest is that once it shifts into 3rd gear the Converter locks-up. I believe it has a sensor for 3rd gear pressure that activates a relay to lock the converter.joeljevning wrote: ↑Tue Dec 27, 2022 9:57 pm Well this is good info, I tried to pull up your link Yeller and it brings me to my orders on Amazon, I'm sure it's an account thing. Can you guys explain the lock up kits on these things, the guy that built the 700R4 said this one was not hydraulic and required 12 volts to it, is that for a lock up? If so do you need to have a pressure switch inline with the solenoid and a switch in the cab?
I fixed the link above, I just didn't click far enough into Amazon deep space to get just the part LOL.joeljevning wrote: ↑Tue Dec 27, 2022 9:57 pm Well this is good info, I tried to pull up your link Yeller and it brings me to my orders on Amazon, I'm sure it's an account thing.

Yes it is possible to split an oil to water cooler inside the radiator and do both fill the radiator with transmission fluid and transmissions with coolant, not common but have seen it. I usually don’t do series on them simply to simplify the cooling systems of both, makes the radiator less expensive too lol. You can add a transmission temp gauge, they are easy to add.
Personally I’m a minimalist on gauge requirements. Speedo and fuel I’m good. Simple light for oil pressure, water temp and I’m good. I do like a temp gauge for testing a new system, but an IR temp gun suffices. Life’s too short to stress out watching a gauge, an idiot light will tell you when bad stuff is happening before it becomes terminal and gets your attention quickly, a gauge you may be distracted and not notice until irreparable damage is done.
