I was wondering if a 4l60e transmission from a 96 GMC is built with better parts than a GMC 93 4l60e trans what I mean is like the parts that are always' shelling out on a 93 4l60e tansmission the same on a 96 model or were they corrected with beefy parts?
Thanks! GMCTRUCKS

You may be right, you are much more in the know than I am. I just started hearing all 4L60E's being referred to L65s in 98 when they went with the removable (shorter) LS-style bellhousing and the 5-pin planet. I've seen a few, and installed a few 98-2001 cars that fit the L65 description, but I have rarely been correct on tranny info when you're involved in the conversation :thumbup: I do know that many of us Impala SS guys looking for upgrades to our L60s turn to 98 and later LS-trannys for the 5-pin planet.
If anyone needs it I've got a recommended parts upgrade list for the 4L60E. I'll be using it to build one soon. It was compiled by a specialist who builds these and 700Rs for quite a few folks and with great success. He gave me this list for my specific needs and he says it should be quite adequate for my engine, which makes around 500 lb-ft of torque at the crank.
Sure they test them. The engineers and designers spend years and millions testing them, then the accountants and executives decide that a plastic part saves 64 cents per assembly and only raises warranty claims 12%, so its a valid change.
Trust me, I worked for YEARS as an engineer for 4 different car companies. The actual amount of our great ideas that make it to production are very few. Some marques are better than others. Some are like McDonalds; use grade F parts that barely qualify long enough to stave off warranty claims, others are like a fine steak house. You pay for it, but the quality is obvious and the prices reflect that.
