Let me make it clear about The Great Overdrive Debate: Should a 700R4 is used by you Or 4L60E?

There comes amateurmatch profiles time whenever spinning that small-block to 3,500 rpm so that they can avoid being go beyond regarding the freeway becomes tiresome. This quickly contributes to considering an update to an overdrive automatic. There are many good reasons why you should select either the 700R4 or the 4L60E. Both provide the advantages of an overdrive, and determining involving the two, the selection boils down electronics or no electronic devices.

If this has a cable connection nearby the cooler lines on the passenger’s side, that is a 700R4.

The very good news is the fact that in any event, you winnings. Somewhere else in this whole tale we’ve detailed the ratios of both the TH350 and also the 700R4/4L60E. Whilst the 3.06:1 First-gear ratio would seem become an edge on the TH350’s 2.52:1, the drawback with all the much deeper very very First may be the major rpm fall when you look at the 1-2 and 2-3 gear modifications that the 700R4/4L60 force upon you. At component throttle, it is only a minor problem since converter slippage absorbs all the distinction.

The advantage that is obvious the overdrive could be the 30-percent decrease in cruise RPM. None with this is breaking news, and both transmissions provide exact same benefits. Now let us enter into the thing that makes them various by first investigating the 700R4. Advantages begin with something which’s essential to everyone – cost. Read more of this post
