4L60E to 700R4 swap

[Hood93z]

Hi guys as some of you know I've been having problems out of my trans wiring harness.. So giving that I just swapped my brothers truck to a 5 speed and he gave me his freshly rebuilt 700R4.

So what I'm going to do is replace the 4L60E with the 700R4 temporally, while I save up some money for a 5.3 and 6 speed auto trans. If I'm happy with the 700 I'll probably keep it for a while install corvette style servo and so on.

Ok I'm running the 700r4 with no harness it's doing great no problems have every gear 1-4 just no lock up

Before everybody tries to warn me the converter I'm running is a non lock up converter

Hey I'm looking to do something similar with 1994 gmc sierra k1500 and 4l60e. Was wondering if it just bolts up like if it were a replacement 4l60e as far drive shafts and transfer case mounts goes.

Perhaps a moderator will move this necro-thread out of "Engines" and into "Transmissions".

If the lockup converter doesn't work, does the cooler circuit still work? I've heard that if the converter clutch doesn't engage, the cooler circuit is disabled. The trans overheats, and the planetary gears and shafts don't get lubed, 'cause that's what the cooled fluid returning to the transmission does--lube the geartrain.

See post #3. With a non lock up converter, I would guess the cooling circuit works.

Overall, I'd prefer to not "guess".

Part of what drives my question, is that I've never been able to verify that on a stock application, with a converter clutch, that if the clutch doesn't engage, it disables the cooler circuit.
