Replacing a 4L60E with a 700R4?

I have a 94 Chevrolet 1500 (4X4 with a 5.7 liter) pickup with the 4L60E tranny. Can I remove the 4L60E and replace it with a 700R4 (and obviously not utilize the computer). If so, will this ''mess'' with the ecm?

Not with good results, the 4L60E is run by your ecm, the 700R4 while looking close to the same does not relie on your ecm for commands,it relies on a cable to regulate your line pressure.

I have an 1993 short wide that i ordered a tranny from B&M, a 700r4. They tranny wires from my truck have a round plug , and the new 700r4 has a square plug. Is there an adaptor for this


your first problem is that you ordered the wrong transmission. in the late 80's chevy switched from the 700r4 to the 4L60E. all the electronics for the 4L60E was changed. the only way you can run the 700R4 is if you put a completely different ECU (computer) in the truck. I recomend you see if you can trade the transmission in for the correct one or you will be going through alot of headaches trying to get another computer and complete wiring harness for the truck.

I have a 99 K1500 Suburban with a weak 4l60e trans. I have a 97 Suburban 4l60e trans available. Will they interchange?


yes. 96-99 are the same. 95 are different. 94-88 are the same. thats the most i can tell you off the top of my head. As long as the trannis are the same type they'll fit. For example a 700r4 from an 86 will fit into a 88 with a minor adjustment. But an 86 700r4 will not fit into a 86 that had a TH-400 without major changes. So as long as they're both 4L60E within the years mentioned above they'll interchange just fine.

Swapped tranny, just need help with matching up wiring


It won't work. The shifting of the 4L60E is done by the computer in the 93. You might check with Summit or Jegs, I think they make a system to make it work.

What year transmissions will fit in my 94 jimmy automatic


GM is notorious for one size fits all, so most any 4x4 transmission will fit. I would stick to close years that can provide the same style transmission, like 700r4 or 4L60, so the electrical just plugs in. Hope this helps.

4l60e tranny swap


No the 4l60e is a electronic transmission you need to find a 700r4 transmission which are very common. Check with your local junk yards and are pretty easy to install. About a full days worth of work for a person with general know how of vehicles.
