Very cool.......Would've liked to got the chance to build a 4L65E for it, Just to show off
A 4l60e or anything in that rotating weight range, is truly ideal for my car. The little Nissan is very light, and I don't use any Tbrake.
But I do not have the skills, space, or patience (even with GREAT help) to attempt a one-off 4l6xe rebuild, I wish. I will in the future if ever reach an opportunity, if you feel up to baby sit me while I fumble and struggle with surface finish on a grand scale.
For now I will have to accept the roughly 3 to 4hp loss of the 4l80e (and resulting 3-4 mpg loss for cruising) Because with very little modification, 4l80e can handle alot of abuse, and I am very demanding driver and impatient to put things into service which is not good when building something as delicate and intricate as a automatic transmission.
The 4l80e, to me is like a beginner transmission, perfect for first timers, its massive, parts inside seem difficult to damage, snap rings are easier to deal with because they are larger and easier to grab, valvebody seems simple and robust. I didn't have any trouble with the valves or roll pins. Nothing broke and slowed me down from ordering and waiting to replace broken parts. None of the snap rings gave me what I would call significant trouble. I was impressed with the 4l80e's ability to make me feel like I knew what I was doing. The sheer size of everything really helps and within a very short time I was able to remember which bearing and which direction, how think each thrust is, how parts 'felt' and whether it was normal or not.
I even put in the AFL upgrade from trans-go which uses a reamer tool... without managing to damage anything.
I was amazed at how resistant the 4l80e is to my harsh nature.
