In my 96 k1500 with a 4l60e Iv been having some abnormal 1-2 shifts.
When I start normally from a stop it it like it’s delayed mushy and late, feels a lot like a stumble
If I get after it from a stop it also feels delayed but it becomes a harsh shift and sometimes feels like it has a slight shudder.
Other than 1-2 the rest of the trans feels good
In my searching I found that alot of these issues point towards a 1-2 accumulator. Or a tps sensor. I used my scangauge to watch tps data and it seems to be smooth and it goes into overdrive fine.
Other than that I couldn’t find a whole lot to match the issues I’m having.
Here’s the most frustrating part. About 6 years ago it got stuck in park. The shop I took it to said the trans had to come out to fix it. So I decided If it was coming out it may as well have a freshen up as it had 220 some thousand miles on it. I ran it for a couple years and started getting hard shifts so I took it back to him and found that the harnness inside the pan had a issue and the valve body wasn’t holding. The shop replaced both at no charge they were great to deal with.
The problem is I don’t know what I did with the invoice and I don’t recall what all parts he used. The total was about $1300 and I know he did clutch packs and the valve body but that’s about all I remember. I called the shop today to see if they had record of what all was done. It would appear the shop has a new owner and the shop has moved. They don’t have any records from the old shop and the guy was not willing to talk to me about it and got ruder when he told me to bring it in so they could look at it and I told him I now lived 4 hours away so that wasn’t a very good option.
So now here I am. I planned on doing a fluid change and pan replacement this spring anyway but now I’m thinkin it might need to be done sooner. Are there any tests or other checks I can do that you guys recomend? It does not feel like it’s pulling itself apart but I don’t think it’s doing it any good driving it around this way?
Regardless of what the issue is what are your thoughts on a sonnax 1-2 accumulator, sonnax boost valve and a corvette servo? I was thinking about doing these when I dropped the pan anyway but I’m not certain if they have been done or not. I was a broke college student so I’m pretty sure everything was stock spec for the most part.
Thanks
The trans has about 50k on it was gone through
