  • 4l80e -vs- 700r4 weight difference

    To avoid any guesses today we weighed both transmissions.

    the 4l80e is 40lbs heavier.

    700r4 is 134lbs
    4l80e 174 lbs.

    I don't know much about transmissions...what kind of advantages are you looking for when going to the 4L80E. I always thought the 700R4 was a pretty beefy trans, especially when built right.

      Even when built right, if your putting 500ft-lbs plus through it on a daily basis and have the traction to control that power, the only thing that is left to slip is the trans......the 700 just can't take the abuse the 80E can. There are other advantages as well (such as gearing change, electronic firmness and shift point control).......However the main one is strength. The 80E was designed with towing, and abuse in mind, and as such it holds up to ALOT of torque with ALOT of traction much better than the 700R4 could ever hope to......The design criteria is closer suited to what the Sy/Ty needs.

          No problem.....there's a bit more to it as well. Involving how the gearing loads the motor, and the ability to change the shift points to suit the powerband of your particular motor. Also the internal workings are a a bit different in how things stop/start to change gears, and the 80E's design in that area is superior as well.

          The biggest thing I've noticed riding in Jeremy's (six-is-enough) truck is the lack of a brutal 1-2 shift that the 700's have. Since the 80E can modulate line pressure electronically, when at part throttle the shifts are crisp, but they don't bang into the next gear like the 700's do. However once into full throttle the line pressure comes up, and you get a good hard shift......Makes driving it around significantly more enjoyable IMO.

          There is a review around here somewhere from the last week, where a guy went through the whole change process, and has nothing but good things to say about it.....lemme try to find that for you.

          *edit* Found it.....Click Here for a 4L80E review

          Now back to your regularly scheduled tranny weight thread.....Sorry for the hijack Jeff

              This is dry weight with no converter correct? Just curious. good info though. I know i lifted my 700 with the converter still in it and then my 4l80 w/o converter and there was a difference, but not as much as i thought...

                    Both weights are without convertor.

                    Jeremy did weigh his stock sy convertor -vs- the one built for his 4l80e and the 4l80e was 2 lbs heavier. I don't know the weights though. I would say the 2lbs there is a wash or close enough to it.

                        Man, thats the one thing I truely love about my truck, is its 1-2 shift and the 2-3 shift. I wouldnt feel right about it not planting me in the seat everytime I shift around town, lol.

                          Yeah, but the good thing about the 80e is that you can set the line pressure so that it shifts however you want during any condition.. You better beleive that I would be dialing in painfully hard shifts under all conditions as well...

                            Just curious. Why would you want it to beat the piss out of you going through a parking lot or parking garage? Don't get it. Maybe that's why some 700s last to the 10s for some guys and others can't get them to the grocery store without a failure.
