4L60e Converter Problems Hey all, just got some questions about some of the problems that I am having. So, My car is a 1994 stock cube LT1 with a mild cam and slightly higher compression with full bolt ons, lowering springs, LCA's, and the stock 4l60e with a cooler. Been super busy here lately and I haven't had time to get the new converter in. I noticed on Monday that the car was acting funky, it would almost feel like it was missing at times. The exhaust note would change and the car would almost feel like it was jerking at times. I know I am not having a misfire because all of my ignition components have less than 1000 miles on them and the car runs just fine in park. Also, I've developed a small rattle/vibration coming from under the center console. After I noticed it acting weird I took it out on the highway and tried doing a first gear pull. The car acted very sluggish, didn't spin the tires at all like it usually does, almost felt like it was slipping, and it just didn't feel like it was getting the power to the ground. I've put about 2000k miles on the stock converter with the new cam, just wanting to confirm my suspicion about the converter before it pops like a water balloon.

Well yeah there are tons of them, just depends on how much **** you wanna throw at it. I found a local guy to rebuild mine for about a grand, has held up great. I'm changing my build to a turbo setup and sold the trans still working instead of risking tearing it up. But properly built it should hold a 10 second car pretty reliably.

My current 60e is the original with 80k on it so I'm surprised it's already shitting the bed. I'm gonna add some fluid because I know the 60e's get finicky when they don't have enough fluid. Couldn't find anything decent locally but I did find a place about 2 hours away. Here is a link to the place I found, let me know what you think!

Sooo, put some fluid in it because it was low. Put in about half a quart. Went and drove the car, got on the high way and tried a pull from 50 to see what it would do. Car kicked down a gear and accelerated fine but it didnt shift correctly. It shifted almost 800 rpms before its programmed shift point. The car shifts just fine other than that. Undee any power it shifts early. Doesn't seem like its slipping at all.
