I got my P1870 code (TCC Slip) checked out at a shop today, and was told I need a new valve body. They want $480 plus labor for a GM replacement that is special order. Is there any cheaper valve body I can get that is performance?

I appreciate any help, I don't know a lot about transmissions

We dont sell valve bodies stand alone however I am sure one of the sponsors here may be able to help you with that, Though you will still have to find someone to install it.

Installation is no problem, I just need to find a replacement and get it ordered

thanks

Mine didn't have the problem when I installed the TransGo SK, but a replacement valve in the kit is supposed to fix/prevent the slippage leading to P1870 setting. Maybe cause new valve rides in an unworn area of the valve bore? Always wondered if it could actually be a fix when code has already set, maybe you could be the guinea pig?

I also replaced the stock seperator plate with the TransGo plate. The stock one had a check ball stuck 1/2 way thru it, not uncommon I hear. One thing for sure, don't keep driving it like that or clutch might get toasted from slippage requiring converter replacement.

Does that kit come with a whole replacement valve body?

I'm looking at TCI's website and they are not specific if it comes with one or not

No its a kit installed in the valve body you have

Maybe you should consider putting a shift kit in? Maybe drop the pan and see what the condition of the oil is first? If the pan is not full of debris a shift kit might be a much cheaper route to take. Feel free to give me a call next week to discuss your options. Vince

I think I found exactly what I need

You could install the valve from TransGo, they run $12.00. It does not require any special tools, and it is a on/off valve now instead of a pwm type valve.

I'm still not understanding any of this, no performance transmission builder has a seperate valve body for sale? I talked to the shop again and they said the GM TSB on the problem called for a whole new valve body.

Thats because thats the only way they will service the problem , Each of the ways here will solve the issue trust me as long as the converter clutch is not allready damaged badly ,
