Hello,
I have just completed my first automatic transmission rebuild, and while I felt good about all the steps it now will shift 1st to 2nd, but never attempt to shift into 3rd gear. (Never attempts 4th either, but I assume this is because it never gets to 3rd.)
Backstory:
I have a 1995 K1500 4wd with 325k miles on it. I purchased showing 215k and it has been great. As far as I can tell this is the original transmission. Last week I was slowing for a red light that changed to green. The transmission was in 2nd then shifted to 3rd and it acted like neutral. Some research made it pretty clear this would be caused by a burnt up 3/4 clutch pack, and bad piston seals. I dropped the trans and just like I read/you tube showed 3/4 was burnt, and the piston seal was hard/a lose fit. I got a parts kit, new 3/4 frictions and steels and re-assembled. Following the Transmission Bench videos show. I expected success.
Now:
When I went for a test drive I no longer get the 2-3 flair it just never attempts to shift out of 2nd. The 1/2 shift is good. Any ideas what I would have done wrong? I have dropped the trans again and everything looks fine. I am at a complete loss, so any theories would be helpful.
Thanks,
Leo
