back when I worked at boeing, a large part I worked on came though with some revision changes. most notably it had large holes in it called out in the drawing as "lightning holes" (yes spelled just like that) and I thought wow these aerospace guys are so smart, adding in places for the lightning to go through in case of a lightning strike.

yeah it was just a misspelling haha

 

I vote that this is made into a stickie!

 

I agree with you. There are stickies with a lot less info than this.

 

I appreciate your endeavors , I've Two 4l80e that I'm rebuilding currently.
I joined this group to find this information. Thank You.

 

 

Our local torque converter builder,, his builds have trophies at the local strip & track.
First trans is a USED BAD $200 gm rebuild. I got to replace one in 2002 GMC 2500hd.
second one i got $40,, broke case running fine , I have a cut case on its way to tig weld that chunk in.

 

I know this was done a few years ago but I wanted to say this is really good information vorteciroc, I can imagine it took a lot of time to do this. From my perspective it looked like you had a job or have a job that could be enjoyable. I would be stoked going to work everyday. When I worked with my dad I was under so much pressure that just pulling up to the shop instantly put me in a bad mood, just thinking about it now makes my stomach turn. If I could have just done the work it would have been ok. Everything else brought the misery.

 

@Admin1 Still think this should be a sticky along with some of @vorteciroc other posts

 

I actually agree here, what they should do is make a VORTECIROC TECH sticky thread and we can submit the ones we find that are helpful and with good info to be added to it. They're a good number of threads and post that are very informative on here through the years.

 

I totally agree with you on this one. A dedicated Vortechiroc section would be awesome!!!

 

I am very interested! I have two 4L80E trannies, one is a 1996 and the other is a 2002. My project is a Chevy S10 that I intend to enter into drag and drive events, and I want to build a reliable 4L85E for this purpose. I have read over this thread a couple of times already. Very interesting stuff. Thank you for taking the time and trouble to educate!

 

I recently purchased my first lathe and a mill came with it. i wanted the lathe to be able to cut down pistons and cut pockets for bearings. Hands down the best tool ive ever bought should have done it years ago! This is an amazing thread, thank you for putting this info out there for us! To an noob trans builder like me this kind of knowledge is invaluable.
