On wikipedia it states :

Several changes occurred for 1994. The 4L60 automatic transmission was replaced with the more dependable and sturdy 4L60E.

Does this mean that the trans in 93`s are prone to problems? I ask as I`m looking at a cheap 93 with only 40000 miles on it?

No, they're fine. The 4L60 is simply a 700R4 going by an updated naming system.
The 1994 and up 4L60E is an electric shift version of the 4L60 (different valve body, no TV cable).

 

Ok thanks a lot. I`ll go and view it.

 

so if i needed to replace my trans id need to get a 700R4 instead of a 4L60?

if i went automatic that is, so hard to find a T56 thats not over 1000

 

A 700R4 is a 4L60 is a 700R4....
But there are differences in the lockup plug configurations between some years.
Also, going from a manual to automatic isn't a simple changeover if you're expecting it to operate like a factory hookup (computer controlled lockup). There are aftermarket kits you can buy though, to control the t.c. remotely. After changing over the trans, controls, and shifter, is whatever savings that's left (hopefully) worth it?

 

The 4l60 is an updated 700r4 that has all the 4l60e up dates except the electronic valve body. Most 700r4 rebuilds incorporate those parts also.

 

sorry forgot to say i already have an automatic

 

If you're referring to the 1987 and prior models, yes that's true. However, the 700R4 was updated in 1988 but still called a 700R4 until the name change in 1990.

 

1993 is the only year of the 4l60 that I'm aware of.

 

In 1990, GM changed the way they named their transmissions for easier reference. The 700R4 became the 4L60 by name.
4 being the number of forward gears, L for longitudinal (front to back), and 60 is a reference number for it's torque rating.
For front wheel drive cars, the 440-T4 was renamed 4T60, the T standing for transverse (sideways).
Force of habit is what kept the 700R4 reference alive.
