Whats up with these dam tranny shops. I have a 93 with 3000 stall. Ist guy installs a B&M shift kit after I told him I wanted transgo. Found out this from 2nd tranny shop who wanted to order a new transgo so he could see what 1st guy did with all the springs. Get it back car feels as if it lost performance at part throttle, not as responsive as it was, but the 1/2 shift hits real hard and all the shift are where I like them to be , but and its a duzzy, the 3rd gear doesnt lock up unless I tap the brake just lightly which triggers it to lock up. A noticeable difference when it locks. The pro is installing some switch to remedy me from having to tap the brake which will allow lock up at WOT. Why ? I had lock up before . Car runs extremely rich now and to top it off it has a slow tranny pan leak and the 1/2 shift softened up dramatically. Its now back at his shop. Talked to transgo they said lockup has nothing to do with their kit. Anyone know why I would lose lockup? Could this be causing my car get poor gas milage. My corsa tips turn cake black on short trips. Im totally frustrated.

I just read RAMANSTUDs thread which is very similar thread. This sucks Ramon, But I had lock up before. Where did it go?

the very first thing that comes to mind are the ground connections on the drivers side of the trans.

It sounds like wiring problems did any connections slip perhaps once you put the pan back on?

Just a thought...

????????
Firmed up or softened?

Also, you shouldn't have lock-up at WOT, so there's no problem there. As for the rest, I don't know.

Doesn't touching the brake supposed to unlock the converter, NOT lock-it?

What's up with that?

I know the lock-up feature is controlled by the ECM, but I just want to share what happened with my 85 Olds 442. After I had the B&M shift kit installed, it would not lock-up either. The mechanic that did it used to work for a GM dealer then went into business on his own, I trust him and still go to him for major repairs. He normally only does fluid and filter changes but agreed to do the shift kit, he does not do any tranny rebuilds etc. Anyway, I took it to a local tranny shop (along with the remaining parts of the shift kit since it has more than one option). This shop has been around for years and is subsidised by the city since they provide services to local townships, police, maintenance, and school districts, also provide trainnig for the local vocational schools. They dropped the pan, pulled the valve body and found a spring that was not the right size and replaced it with another one, voila, now I have lock-up. I know this because they handed me the spring that was in there and showed me the difference between it and one they put in to fix it.

I'm not mad at the mechanic who put in the wrong spring, probably just an honest mistake and he still charges me less than his normal hourly rate for services. In fact when I told him what happened he gave me a huge discount on my next service.

Just my experience and .02 cents worth.

After thinking about this some more I am interested to know why your car is running rich. Have someone hook up a scan tool and verify the computer is goining into closed loop. If it is then I would look at the o2 sensor values, BLMs, etc. The trans locking in fourth only is not a problem in my book. Taping the brakes in 3rd and having the coverter lock is though. Tapping the brakes should cause a unlock condition. Also I would not set the car up to lock at WOT, the converter clutch can not take the abuse and will fail.

Also if your trans. guy is a Pro, he will have a scan tool. Then you can take your car for a drive will the scan tool is connected and if the ECM is commanding the converter to lock and the converter does not lock then you have verified you have a problem.

allright guys, I misinformed you a little. Its opposite what I said about the lock up. You have to tap the brake for a unlock condition. I talked to tranny shop a little bit ago and hes still trying to figure out away to put in a switch that will allow for unlock condition at WOT. Also he thinks my band is wearing out causing the the 1/2 shift to soften up. Tanny has 46000 miles on it.

When I first got it back it was very firm, then within a week it softened up alot. Tranny guy thinks its a possible worn band. I should of never messed with the tranny at all.

OK thanks for the update. What about the scan tool? I have seen you post before about your car running rich, if he has a scan tool now is the time to find the problem.
