'94 4T60-e shifting problem

[AWeb80]

It has been having shift problems from 1 to 2. EVERY other gear works perfect. even the down shift from 2 to 1 is perfect....just the upshift is delayed like a MOTHERFUCKER.

here is a quick vid...I was at...maybe...40% throttle at the most....should have shifted at 2500 RPM....then when it did shift at 4k, it rev'd up before going to second. If I get to 15mph or so, throw it into N, then back to drive it will fall in to second or third, whatever is normal for that speed/throttle input, and work fine. If I go WOT, it will bounce off the rev limiter about 15 times before it will shift.

It did this a few times before I left for Toledo this past weekend, now it's every time.

Leander helped me rebuild this ~9K miles ago....I was really hoping for a trouble free trans for a long time.

any ideas?









Just drove it again tonight.....the more I think about it, I wonder if the line going to the accumulator came off so it's not getting enough pressure to shift on time......or maybe the shim I have inside the 1-2 is blocking something...or a spring broke.... Every other shift is fine....just the 1-2 upshift is delayed.


Thoughts?

I had the same problem but never looked into it. I would think if the accumulator line was off or something happened to that, it would mess up every gear and just the 1-2 upshift. Maybe its a shift solonoid?

Man, sorry to hear this problem's gotten worse since Toledo. Hope it's a simple fix.

Easiest thing to do at this point is pull out the accumulator assy and check for broken springs or a seal/ gasket issue

[AWeb80]

yep, that's what I'm going to do.....in a few months when I feel like it.

bump for any more possible ideas.

I think I 'may' have time to drop the pan, acum. and take a looksee.....in about 3 weeks. I really hope shit isn't stuck in the valve body......
