    A4LD won't upshift at full throttle

    Looks like the -20~s are going to hang in most of the week. Parts came from a dealer, had to order them in, sounds like they are not going to be available much longer, older parts I guess. Drained out a few quarts of oil/Lucas and put ATF back in, now I am wanting to warm it up and test drive it...

    A4LD won't upshift at full throttle

    Oh yah and when I pulled the old governor the piston that I had cleaned up was hanging up fairly tight. To snug of a fit into the stalk by my guess so maybe the new assembly will help

    A4LD won't upshift at full throttle

    Well I got the new governor weight and stalk installed and have not been able to really take it for a real test drive yet. Left town for work for a few weeks then got home the other day and it was -46, not quite test drive weather. Still -26 right now, suppose to warm up next week maybe then...

    A4LD won't upshift at full throttle

    Ok rebuilt second donor VB and installed it tonight. Little Lucas and tranny fluid and out for a test drive. Now I have different problems still won't shift correctly but now it is at like 3400 rpm's at 55mph and when I put the shifter in drive one and second it is like the brake is on when I...

    A4LD won't upshift at full throttle

    Ok, called our local parts house and they don't stock the governor assembly neither does our local ford dealer. I am thinking about flushing the system a time or two with some kind of flush like that Lucas treatment and see if that might unstick some stuff. Got nothing to loose with trying it...

    A4LD won't upshift at full throttle

    Wood1 Well I went as far as reinstalling the original modulator and absolutely NO change in shifting. So you think it is the governor stalk/piston assembly? I did like you said buffed it all up and it seemed to move freely so I thought that may have been it. Even behind the modulator i...

    A4LD won't upshift at full throttle

    Ok bought a new modulator it is identical to the one that came in the rebuild kit. Got the old modulator and hooked it up to a vacuum hand pump and pumped it up, it seemed to work ok and compared how much vacuum it took to actuate it compared to the new one. The new one and the one from the...

    A4LD won't upshift at full throttle

    Just found a vacuum leak at the brake booster and sealed it up with some shoe goo, not sure if that could be effecting shifting but since that take is off the same tree as the vacuum modulator and it is all vacuum controlled I guess it can't hurt. Took it for a test drive again and noticed that...

    A4LD won't upshift at full throttle

    So the atsg manual says • all upshifts harsh/delayed or no upshifts 1. Improper fluid level (not it) 2. Manual linkage --'misadjusted damaged. (maybe) 3. Governor sticking (not it) 4. Main control pressure too high (how)? 5. Valve body bolts -- loose/ too tight ( not it) 6. Valve body dirty/...

    A4LD won't upshift at full throttle

    Wood1 so did you have the same symptoms? After polishing up all the governor parts it all looked great and moved freely. So the modulator I got came with the rebuild kit maybe I should put the original one back in?

    A4LD won't upshift at full throttle

    Well the piston in the governor was sticking, cleaned it up until it was free and put the larger upgraded weight on it and put it all back together. Test drive netted the same high rpm shifting but it does shift through all gears and the torque convertor even locks up and runs about 2300 or...

    A4LD won't upshift at full throttle

    No it does not shift manually either but does shift if redlined and you have to back off the gas a little. I did put a new modulator in the came with the rebuild kit, should not need adjusted I wouldn't think? Wonder if I should try the old modulator just for grins? The only thing that I have...

    A4LD won't upshift at full throttle

    Ok so I got my upgraded valvebody installed and it does shift through all gears and the torque convertor does lock up but I to have to run it up into the red to make it shift. Could it be the gov? I have a new weight for mine and will change it tomorrow and see what improvements it makes. It...

    A4LD won't upshift at full throttle

    The atsg manual has very detailed troubleshooting guide to help you determine where to start at. Maybe a sticking governor? I am going to install my rebuilt valve body right now. I did the full upgrade on it and ordered a new governor weight along with new servo pistons and a few other odd...

    A4LD won't upshift at full throttle

    Post 3 covered it pretty well, the adjuster is on the firewall where the cable comes through on the engine side. Mine is like a grey round thing in the cable with a metal button type thing that you press and that allows you to pull the cable out. Then I think it says to with the explorer off...

    A4LD won't upshift at full throttle

    Got it, just discovered that it would not fit the other way anyhow, spring would not allow the plug to fit the other way. I only have one spring on the large side, wonder if that got overlooked while putting the shift kit in? Got about half the valves in tonight, calling it quits for the night...

    Question about bore 205 there is the first part behind the plug. What direction does it go into the bore? One side is open and the other closed, I think the open side goes out and will try to post a picture but not for sure. The picture in the astg manual does not clearly show it, and it is...

    A4LD won't upshift at full throttle

    Well what caused this whole thing to start was a blown out front seal. While I had it apart I put in the shift kit, it never recovered fully. Sent it back 400 miles away to my brother, he drove it around for about a week then lost all forward except low. I get it back and assume the forward...

    A4LD won't upshift at full throttle

    First valve body did lock up, tested as you said. Shifted really bad though, found a knick in the boost valve piston thought maybe that caused it to hang. Installed a second valvebody off a doner that looked in bad shape(lots of gunk) in the pan. Cleaned it up a little and installed and...

    A4LD won't upshift at full throttle

    Shift kit instructions made it sound more mystical. Something about making 1/8" adjustments until it down shifts between 2 and 1 and 3 and 1 at 20 mph? Did not really understand it, maybe when I get there it will be more apparent. So did your valvebody rebuild go good? I am still suffering...

    Sorry "lockdown". Darn spell check!

    A4LD won't upshift at full throttle

    Cable adjusted One of the things that I overlooked was the kickdown cable adjustment. The shift kit instructions point out that the cable needs to be adjusted differently after installing the shift kit. I am again rebuilding the valve body and ordered up some new parts to include the indexer...

    Are my "rpms" too high?

    Eratic shifting Nope had strange shifting in all ranges but that was due to some other sticking valves in the valvebody. The no lock up in OD was the MAP sensor I am thinking. What is it that you are seeing with your ride?

    Are my "rpms" too high?

    MAP sensor code and TCC not locking up Well I did have a check engine light and it did code out as a MAP sensor. So if you have that code it is probably the culprit. If you had a spare sensor it might be worth trying. Another post I read said to check the wire harness on the drivers side...

    Are my "rpms" too high?

    Bad MAP I did have a bad map sensor and it did in fact prevent the torque converter from locking up. Once changed the TC did in fact lock up. I just got through rebuilding the valve body also, had a few sticky valves. Hope to test drive it Monday and let you know what has happened
