I have searched and searched and all the similar problems I can find people just say to adjust the TV cable. I've done this many times by pushing the piece in, and then flooring the pedal, and listening for the clicks. My cable is adjusted properly. There must be something else. My transmission still takes a long time to engage second gear when downshifting from third. Engine responds to throttle, but its almost a full second before I actually feel any pull. The tranny just does funny things. Any thoughts on this?

 

My transmission does some other funny things. When in D, when it shifts back into first as I'm coming to a stop, it lets out a loud, solid KNOCK. It sounds like somebody is smacking the transmission case with a brick from the inside. Its definitely not an external mount, I've replaced everything with poly recently and no change. Doesn't make the noise with the shifter in OD.

 

ttt...?

 

Sounds like the bands and clutches are going out to be honest. That's just from your first post though. I have no idea about the knock but, I would be concerned. This is from the transmission downshifting on its own correct?

 

About my first problem, I have also noticed that sometimes if I floor the car in first gear while going around a corner the engine just revs all the way up like I'm in neutral. I notice and quickly let off so I dont over-rev, and once I get back down to a sane RPM the car goes like normal.

About the problem in my SECOND post, about the knocking sound: I dont know if "downshifting" is the correct way to put it, because I dont know exactly how a 700R4 works, but I would assume at some point while coming to a stop the transmission has to go back down to first gear. When in D (as opposed to overdrive) there is a loud KNOCK when coming to a stop usually associated with some kind of lurch in the car as I am braking, it seems to become easier to stop once the knock has occured. I also hear something in the same situation when I have the shifter in OD, but this is more like a bunch of clicking and random noises and is much less noticable.

When I put the car in OD from Park or Nuetral I hear all kinds of commotion coming from the transmission, like the whole thing is just bouncing around under the car. If I go into drive directly from reverse, the transition is smooth as silk, like a new car. I said it once and I will say it again, NO EXTERNAL MOUNTS ARE BROKEN.

Not to mention the thing leaks fluid like a ****, right where the cooling lines attach. Poor thing is in such sad shape. Gotta give it credit though, I beat it to death every day and the symptoms haven't gotten any worse in almost a year now since I've had it.

Yeah, I think I'm going to need a tranny soon

 

You most certainly will just due to your first problem. You are even more likely to need one now that we know you're leaking fluid from the cooling lines. That's going to cause poor cooling for your tranmission and that will kill an automatic.

The transmission does downshift on its own if you leave it in a higher gear. The knock throws me for a loop. What type of lurch is it doing? To the front? To the back? If it's making comotion like that and it's not your mounts, are you sure you're still bolted to your engine? If all that checks out it might be something wrong with the major stuff inside the transmission like the gears, etc.

 

Man... Been in the same situation as you. I just sped up the problem... Tranny would hold 1st and wouldnt up shift at wot. So when day i got pissed and just held it at wot.... Boom! TRanny was no longer. You could have a problem with MLP (main line pressure) Caused by wear. As your clutches and everything starts wearing the tranny oil pressure isnt enough to compress the clutches (the grab). Good luck

 

lol, so what does a tranny do when it blows? I guess I should be prepared. Does it usually go on hard acceleration? When changing gears? Or will I just one day put it in drive and feel like i'm in nuetral?

 

Short answer to all of the above:

Rebuild time. No one here can tell you what is broken inside - my *guess* is the low/reverse clutches are gone, and the knock is the piston forcing it hard into the steels. With one or more clutches out of material itthuds, rather than works.

The commotion is anybodies guess.

When mine went (V6 with 235k miles - verified original 700R4 - no rebuilds!) I just lost 3rd and 4th. It spent a week slipping out of 4th on the freeway, then one day it didn't go back into 4th, just revved. Then I only had 1 and 2, so I drove on the surface streets to work. When selector was in D or OD when it got to where it should have shifted, it just revved.

When my tranny on a 4 cylinder mustang went, it was on the freeway too - it had been slipping quite regularly out of 4th too, but I could get it back in by matching revs (actually getting the revs just right, then it would "stick" again). It died by slipping out of 4th, then never going back in too. But it wouldn't ever go again in any gear, just rev.

My mom lost a tranny in her 302 79 berlinetta, it made a ton of commotion like parts rattling up and down, then it just wouldn't go.

I lost one out of a 86 grand am. It wouldn't let 4th gear go, so when you got into 4th with TCC applied it just wouldn't un-apply - stalling the engine when you hit a stoplight. Unplugging the TCC solenoid fixed it. Eventually I got rid of it for that problem.
