700R4 2-3 shift problem
Last weekend I got my vette out after a month and a half hiatus. 5 miles into my cruise after taking a turn and accelerating moderately the tranny shifted into OD was holding speed and all of a sudden it revved up like it was in neutral. The car no longer has 3rd or 4th gear. Reverse, 1 and 2 are OK but as soon as it tries to automatically shift or I manually shift into third it just revvs. Has anyone had this problem? I doubt it is a clutch pack problem due to the suddeness, could it be a valve body problem with a a valve sticking???? If you had the problem what did you do to correct it?
Thanks

Had that exact problem with my '87 vette after flooring one day to pass a car on the road, just kept revving and wouldn't shift into 3rd or OD. I could drive the car as long as it didn't shift (manually put it on second gear). Sorry to say, but you most likely lost your internal clutches. I don't know the proper terminology for it, but whenever you do the rebuild, be sure to ask for the update 3-4 clutch pack and try to get a shift kit on it. With firmer shifts, the tranny lasts longer due to less "riding" of the clutches.
Unless you're a 700R4 guru, You're looking at a rebuild, I've taken one apart and realized it wasn't worth my time, effort, and money to buy the tools and parts neccessary for rebuilding a tranny.

Well, a few weeks prior, I noticed that the 2-3 and 3-4 shifting was a bit smoother than normal, nothing real unusual, then out of the blue... GONE!...
I asked the guy that rebuilt it about it's condition. He told me it was pretty bad, clutches were worn badly, I had a planetary gear that wasn't good, and some other things. With hardparts and all, I paid less than 800! And that included a shift kit and all the updated parts and higher quality friction material as well as a rebuilt torque converter!

I have had the same problem also. It turns out to be the 3-4 packs are bad. I am on my thrid trans in 5 years. Have it rebuilt or buy a new one from Chevey for around $1,200. With 3 year warranty.
