Hey guys I have a 4l80e with a full manual valve body conversion with zero electronics except for the converter lock up. So I've been having an issue with my 1-2 shift when the trans gets up to temperature the shift takes a second to happen and its lazy sometimes... I talked with a 80e builder at hughes performance and he said the shift solenoid is leaking or the linkage is off. So I checked the linkage and it's perfect, then looked for the shift solenoid to replace it and found theres a plug instead of a solenoid. And sure enough the o ring on the plug was garbage and the plug could just be wiggled and moved all around. I've tried looking everywhere for either a new plug/o ring but I havent had any luck and its driving me insane so I'm wondering if anyone knows where I can get the new parts or some other solution. Heres a picture of both solenoid A and B plugs

 

Who built the valve body with the plugs?
Have you reached out to them for a new one?
Also, if you need just the o ring, I would *assume* that it uses a standard solenoid o ring....any trans shop local to you should have 100 of those o rings just laying around. Ask for one

 

The trans came with the car when I bought it but i know it was built by Midwest converters. Called them and i was told they'd look for the paperwork on it but never got back to me. I tried a stock solenoid o ring but it was way too skinny and the ID was way big

 

Might be a zero gravity kit.
Give them a call and send them a picture...they might be able to help.

 

I saw that too, emailed them almost a week ago and still no response. I might have to just call I guess maybe they dont check their email or something lol

 

Gotta pick up the phone if you want a quick response from anybody worth their salt in this business.
It's usually the best way to get the info you want anyway...an email chain with 10 followup questions can be replaced with one phone call

 

If its from Zero Gravity throw it in the garbage and start over.

 

😂😂😂😂 seriously, if I didnt have to pull out my trans I'd have your d1 brake in the car already.
