superquest Posted July 11, 2008 Report Share Posted July 11, 2008 Im having my 89 Quest auto tranny rebuilt by a shop in a couple weeks and have been told to get my valve body upgraded and add a shift kit because this will fix all with our auto trannys.What kind of price for product and price for install am I looking at?

MikeMeyerhoff Posted June 9, 2010 Report Share Posted June 9, 2010 Valve body upgrade?From where?Any companies making them?No companies. its not a new part, just modifying an existing one. You can PM Balt above as he does (or did) them for folks for a fee. You can also do this yourself with some effort. The instructions are found on starquest websites if you look. Or you can google L4N71b valve body Link to comment Share on other sites More sharing options...

kstokes606 Posted November 15, 2010 Report Share Posted November 15, 2010 (edited) Can I do the same mod on my D-50 truck transmission? I have a 1988 D-50 custom cab 2wd auto, and I want to find a shift kit or mod for it, to give it a faster shift, and harder shift.

The Rabbit1 Posted March 13, 2011 Report Share Posted March 13, 2011 Actually found a youtube video: http://www.youtube.com/watch?v=aIs5d1GWXUMthat is not the same transmission. our cars have a L4N71B transmission. And no one in the US makes a "shift kit" for our transmissions. While the valve body upgrade from that trans may work, it may be a horrible mistake. I called Trans-go myself and asked about any upgrades for our transmissions and they said the mazda counterpart has a shift kit available but ours does not and it will not work on our transmissions. So I wouldn't recommend it. But maybe they just never tried it? Link to comment Share on other sites More sharing options...
BaltTSI Posted March 13, 2011 Report Share Posted March 13, 2011 I can tell you if it will work, just give me some time to look at the video, I gota run right now! Link to comment Share on other sites More sharing options...
BaltTSI Posted March 13, 2011 Report Share Posted March 13, 2011 (edited) Ok, I thought that was going to be a long in depth video, not, one reason it won't work...the music is all wrong! But seriously, that is nothing like the mod for our tranny, first of all if you go and start taking the valve body apart...which it didn't show, your going to have tiny parts falling all over the place that you may not be able to figure out how to get back in the right place.And I don't have a separator plate in front of me to compare to theone in the video, but the mods to that are completely different, and one spring in one valve? not a mod that I'm familiar withfor our trans.

theRobot Posted April 22, 2011 Report Share Posted April 22, 2011 Yea, the valve bodies in our transmissions have two small ball bearings and springs that push against the separator plate. I took my original one apart thinking that was the reason the transmission wasn't working, so I got some first hand looks at the valve body assembly.
