rockfangd Posted August 13, 2009 Report Share Posted August 13, 2009 Ok so i went from my 1994 oldsmobile cutlass supreme 3100v6 4t60e trans to a 2000 Chevrolet Lumina 3100v6, (unsure whether i has the 4t60e or 65e) and I hae driven this lumina 50 miles as of tonight. So the problem i am having is compared to my 94 olds the which shifted very smoothly, this luina seemsto kick a little too much for my liking. I dont want to start worrying about this until i know for sure. Before tonight i thought maybe it was because of the battery being disconnected for months and replaced after about 10 miles of driving, but i am not sure if the drive cycle or idle relearn could cause this because since i started driving the car last friday it didnt idle properly when it is first started. I tried driving a little more aggressive tonight and here is the example of how it happened from a stop with moderate acceleration from first gear to second gear it shifted at around 2800 rpm and it seemed to kick into second. from second to third it shifted around 2500 rpm and you can feel it kick into third from third into O/D it shifted around 2100 rpm but it seemed to flutter for a second before the TCC locked in. Upon acceleration from tcc lockup all seems fne. The tcc disengages fine and it picks up fine. When the trans shifts gears i have not noticed any fluctuationin the RPMs that seemed abnormal. Any opinions on this are highly appreciated. I know the engine needs a tune up and the trans fluid is a bit dark, but no darker than normal. I planned on changing the fluid and filter on saturday, and also doing the tuneup, but i dont want to cause any damage to anything. I am not going to drive the car again till next week when i have a better knowing of the situation. Thanks to all in advance and sorry for such a long post but i was as specific as i could be Quote Link to comment Share on other sites More sharing options...
88red4cyl Posted August 13, 2009 Report Share Posted August 13, 2009 I don't know about the flutter, but the rest sounds about how the trans in my LTZ acted when I would lay into it a bit... Quote Link to comment Share on other sites More sharing options...
rockfangd Posted August 14, 2009 Author Report Share Posted August 14, 2009 Does this all sound like somthing that i should be worried about? Quote Link to comment Share on other sites More sharing options...
shuck Posted August 14, 2009 Report Share Posted August 14, 2009 I'm not a 4T60E (or 65) expert, but that sounds like the way a transmission behaves when the kickdown cable needs adjusting. I'm sure that's not the real name for it, though. I've had a number of other cars that would shift with some kick and it was usually due to a poor adjustment in the throttle / transmission kickdown cable. Hope that helps - let us know if you figure out what the problem was. Ryan Quote Link to comment Share on other sites More sharing options...
GP1138 Posted August 14, 2009 Report Share Posted August 14, 2009 Do the "E" transmissions even have kickdown/detent cables? Quote Link to comment Share on other sites More sharing options...

Galaxie500XL Posted August 17, 2009 Report Share Posted August 17, 2009 Check the vacuum modulator, it controls line pressure. If the diaphragm is broken, or the vacuum line is detached, it can cause the symptoms you describe. Quote Link to comment Share on other sites More sharing options...

Crazy K Posted August 18, 2009 Report Share Posted August 18, 2009 Don't bother... your car should have a 4t65e http://dtcc.cz28.com/transmission/index.htm it does not have a vacuum modulator. double check if needed! Quote Link to comment Share on other sites More sharing options...

You are correct. It is the 4t65E, and there is no modulator. Quote Link to comment Share on other sites More sharing options...
rockfangd Posted September 1, 2009 Author Report Share Posted September 1, 2009 Ok so this is where i am at on this situation. I changed the fluid 2 weeks ago which made little difference. The only reason why I couldnt change the filter is because It was too late to get the correct filter kit(i bought the wrong one) So 2 days ago I put a new filter with 7 quarts of Dexron Mercron synthetic High mileage fluid from valvoline and a quart of Lucas Trans sealer and conditioner. I drove The car 25 miles and the pickup and shifting was great. But then today I drove 45 miles and noticed that all is fine till I drive for a while and then it starts shiftig harder, and almost feels like it sips when it goes into TCC lockup. Today thought I almost heard a very slight whine upon acceleration. Basically it shifts fine when it is cool but as it gets hot it isnt right Does this sound like the trans is going out? Maybe theres nothing i can do with it? I have never had trans problems before so this is new to me. Quote Link to comment Share on other sites More sharing options...
Regal_GS_1989 Posted September 1, 2009 Report Share Posted September 1, 2009 Personally, I would not have gone to a synthetic trans fluid, especially after doing only a pan drop. When I worked at the trans shop, I recall someone with a lesabre having the fluid changed with synthetic and it was fine at first, then it started acting up. We told him to dump it and go back to regular and he just didnt believe us...Needless to say, he finally let us change it back to regular fluid and it was fine after that. But from the sounds of it...it could be either the fluid causing it to slip a little bit, and the ECM is correcting that increasing the line pressure to compensate, or the Pressure control solenoid could be starting to fail (common enough issue).

rockfangd Posted September 2, 2009 Author Report Share Posted September 2, 2009 well being it was doing it before i changed the fluid and before i changed to synthetic. Can the pressure solenoid be replaced without loads of work Quote Link to comment Share on other sites More sharing options...
Brian P Posted September 2, 2009 Report Share Posted September 2, 2009 how are you controlling the pressure control solenoid in a '94 car? Your PCM doesn't have provisions for that unless I'm missing some other info about this setup. Quote Link to comment Share on other sites More sharing options...

Brian P Posted September 2, 2009 Report Share Posted September 2, 2009 oh...OH!!! I thought a '00 Lumina trans was installed into his '94 Slutless Nevermind!!! Quote Link to comment Share on other sites More sharing options...
rockfangd Posted September 2, 2009 Author Report Share Posted September 2, 2009 very sorry. I have not removed my cutlass from my profile. The 94 is vacumn modulated. But my 2000 is not. I need to know if the pressure control solenoid can be replaced without tons of work? Quote Link to comment Share on other sites More sharing options...
Brian P Posted September 2, 2009 Report Share Posted September 2, 2009 you'll have to remove the side pan to access that solenoid, so yes it's a pain in the ass to change it. Usually the trans has to come out, though some people claim that the side of the frame can be dropped enough to access it. Quote Link to comment Share on other sites More sharing options...
rockfangd Posted September 4, 2009 Author Report Share Posted September 4, 2009 Ok so after extensive research it seems that the pressure control solenoid is extremely common to the 1997 to 2001 to malfunctioning. All of the symptoms match what i am running into. My question is can anyone guide me in the right direction to changing the pressure control solenoid? Has anyone pulled this before? If not maybe someone knows where i can get directions on the procedure. Thanks to all This car is very nice but This problem will worry me until it is fixed because i know it is not right.

rockfangd Posted September 20, 2009 Author Report Share Posted September 20, 2009 Ok so here is an updatethat may help figure out this I know when the transmission is going to start acting up because i can hear a winding noise coming from the trans and that is when it acts up. If I drive highway I have no problems but stop and go is when it acts up. So if i shut the car off for about 10 minutes it is ok for a little while. I dont want to change the PCS and TCC solenoids if there isnt a chance that the could fix the problem Quote Link to comment Share on other sites More sharing options...
rockfangd Posted October 6, 2009 Author Report Share Posted October 6, 2009 Ok so this issue is really starting to bother me too much. I am afraid that the trans is going to go bad unexpectedly. I cant stand the thought of something being wrong and not being able to do anything about it. I called around and the cheapest I can find to have it rebuilt is 1,200 which i cannot afford. I dont know if it is worth taking a chance on replacing the Pressure control solenoid and TCC solenoid because it is not a very easy job and I do not know if it will fix the problem. Also I do not even know how to pull the sidepan. I am afraid to drive the car because most of the time I am in the car for 2-4 hours at a time. When it starts to act up I just baby it as much as I can and try to shut the car off for awhile. I like this car other than the trans issue but I am really at a loss of what to do with this. anybody have any opinions. Quote Link to comment Share on other sites More sharing options...
Brian P Posted October 6, 2009 Report Share Posted October 6, 2009 Rockfangs, The whining you are hearing is likely the oil pump while producing max pressure. The old 4T60e pumps also sound like that when you disconnect the vacuum line going to the pressure modulator which consequently maximizes fluid pressure. There's not much else you can do about it other than replace the failing part. The pressure control solenoid is Pulse-Width modulated, so it's not like you could give it a different electrical input from somewhere else. The only thing you may be able to do is keep the tranny as cool as possible (add a large cooler), since likely the solenoid is acting up once the tranny is well and hot. It may buy you some time before it acts up again though. Has anyone on ClubL67 changed the solenoid while keeping the trans in the car?
