93 should be the 4L60 controlled by the throttle pressure, the 4L60E is controlled by the ECM

As you accellerate easily you should feel as if the tranny is shifting into another gear at 48-49 mph...this is the converter locking up...once it does and you are cruising at say 70 mph, if you lift off the gas pedal your rpm will not immediately drop...it will stay up for a few seconds...this lets you know your converter is locked as well....
FWIW, non-lock up converters are used mainly at the drag strip...on the highway they cause way too much heat in the tranny and will hurt it fairly quickly...

No he shouldnt. No 1993s came with a 4L60-E
No you think wrong. Not 1 single 1993 model came with a 4L60-E. The converter clutch doesnt lock based on RPM, it is the only part of the trans controlled by the ECM and it is based on a TPS% versus MPH table, 1 table for lock and another for unlock in OD, and 1 each for lock and unlock in normal D.
5 tables in total, listed at the bottom of page 2 on here: http://www.tunercat.com/pdfs/ecm_$da2.pdf
100% spot on. Still amazing how many people seem to think that some late 93s had the 4L60-E and early 94s had a regular 4L60.
Both are wrong. All 1993s left the factory with a 4L60, and all 1994s left the factory with a 4L60-E. The 1993 ECM doesnt have the ability to comand the automatic tranmission to shift on a 4L60-E, the 1994 PCM has 100% of control over the functions of the transmission and the 4L60-E trans cant shift gears without it. There is nothing in either 93 or 94 service manual to state otherwize.

i tried to use a 4l60 trans filter and the neck on the filter was to big. the parts store said it had a 4l60 in it too, but i tried the 700r filter and it fit perfectly. is there anything on the outside of the trans that you can use to identify a 700r from a 4l60?

No mate they are pretty much the same trans, only the name is different. The 4 means it has "4" forward gears, the "L" means its a Longitudinal mount (as apposed to a "T" for transverse mount), and the "60" is a relative torque capacity.
