SUPRA FLY Posted April 20, 2004 Share Posted April 20, 2004 Hi guys! I have an NA auto and over the last couple of days am sure I have expirienced power loss. 1) When trying to accelerate the rev goes up rapidly but the speed doesn't. 2) Once the speed picks up the rev drops fast and hence the acceleration drops again. It doesn't do it all the time as well..........sometimes its fine....am confused. My first guess was the gearbox. Has anyone else had the misfortune to expirience this? Does anyone know whay this is happening. The car is under warranty so am not extremely worried at this point. Any help will be appriciated.

Supraguy Posted April 20, 2004 Share Posted April 20, 2004 Torque Converter slipping? Link to comment Share on other sites More sharing options...
SUPRA FLY Posted April 20, 2004 Author Share Posted April 20, 2004 Thanks Supraguy! How do you fix that? More importantly is it expensive? Link to comment Share on other sites More sharing options...
Terminator Posted April 20, 2004 Share Posted April 20, 2004 Have you checked the level and condition of your ATF? Link to comment Share on other sites More sharing options...
SUPRA FLY Posted April 20, 2004 Author Share Posted April 20, 2004 ATF? Someone thinks it might be the Torgue Convertor oil needs changing. I run the car for a while and checked the oil and its dark brown and I believe it should be redish in colour. Link to comment Share on other sites More sharing options...
SkyJawa Posted April 20, 2004 Share Posted April 20, 2004 ATF = Auto Transmission Fluid. Should be red. Link to comment Share on other sites More sharing options...
Supraguy Posted April 20, 2004 Share Posted April 20, 2004 Deffo should be red! Your ATF is the same oil that feeds into your TC. Link to comment Share on other sites More sharing options...
SUPRA FLY Posted April 20, 2004 Author Share Posted April 20, 2004 Thanks guys:) Looks like this oil needs changing and am lookin to get it done this weekend.... Link to comment Share on other sites More sharing options...
dangerous brain Posted April 20, 2004 Share Posted April 20, 2004 How often does this oil need replacing?? Link to comment Share on other sites More sharing options...
SUPRA FLY Posted April 20, 2004 Author Share Posted April 20, 2004 Wait wait wait I know this one...... TC is Torgue Converter I think which is effectively the clutch on a manual....I think The traction control I think is built in an NA and hence you can't switch it off... Am startin to learn a little about these machines man....check me out. Link to comment Share on other sites More sharing options...
SkyJawa Posted April 20, 2004 Share Posted April 20, 2004 Its every A service on the schedule for changing isn't it? Mine had just been done Link to comment Share on other sites More sharing options...
TRD3000GT Posted April 20, 2004 Share Posted April 20, 2004 Torgue is meant to be Torque. Any your car has no traction control, Just ABS. Link to comment Share on other sites More sharing options...

TRD3000GT Posted April 20, 2004 Share Posted April 20, 2004 it could be 3 things. Clutch , torque converter, or just tranny oil. Im not to good on Auto Boxes but ill have a look later. Link to comment Share on other sites More sharing options...
Chris Wilson Posted April 21, 2004 Share Posted April 21, 2004 Slipping auto boxes are BAD BAD news, if it's not already buggered its life will have been dramatically shortened. The clutch and brake bans withing have paper thin linings and the heat of slippage will either de bond them from their backing plates and strips or burn off the material virtually instantly. The detritus gets into the torque convertor and oil cooler. I believe you are looking at a new gearbox and torque convertor and a cooler and line flush. It is impossible to clean out torque convertors without dismantling them. Aisin Warner repair parts are hard to get in the UK, VERY expensive and the box is complex. A secondhand box and convertor would be the cheapest option, but would have to come from a N/A car, the TT is different. It's probably been caused by low fluid level. Check it and top up if required using the CORRECT stuff. Read up up on HOW to dip auto box oils, it's totally unlike the way you dip the engine oil.

TRD3000GT Posted April 21, 2004 Share Posted April 21, 2004 Le bought the car 1-2 months ago so I hope its not that serious. Anyway I dont think it is sliping. Ill have a look later today. Le come over after work and Ill give it a drive and tell u whats happenin. If it is , it is under warranty! Link to comment Share on other sites More sharing options...
TRD3000GT Posted April 21, 2004 Share Posted April 21, 2004 whats the way to know if the box has been well and truly shagged? Brown oil ?? Should it always be RED Link to comment Share on other sites More sharing options...
Supraguy Posted April 21, 2004 Share Posted April 21, 2004 Brown oil could simply be it hasnt been changed in ages. Change your ATF asap and then see what it does! Dont waste time troubleshooting if it can be resolved that easily. Link to comment Share on other sites More sharing options...
TRD3000GT Posted April 21, 2004 Share Posted April 21, 2004 ok. But le spoke to one company who said that if the oil was brown then the GB was shot? Sounds like a load to BS to me! All oil goes brown once it has been worked. Thats what its there for! I need to see this car tonight to see if it is slipping! It might not be. Is it possible it could just be the clutch?

TRD3000GT Posted April 21, 2004 Share Posted April 21, 2004 that covers that then Link to comment Share on other sites More sharing options...
Supraguy Posted April 21, 2004 Share Posted April 21, 2004 A TC (Torque Converter) has the same function as a clutch in an Auto Transmission. Thats why I first said, it sounds like the TC is slipping. Your ATF should be red, or atleast a tinge of it. If its ever gone brown it definitely needs changing. Change this before you do anything else. Driving on bad oil wont help the thing in any way. Link to comment Share on other sites More sharing options...
SUPRA FLY Posted April 21, 2004 Author Share Posted April 21, 2004 I hope its what you say it is. The car is going to Jemca this Friday for inspection and ATF change. Mr Chris Wilson is saying that if the oil is brown then its more than just a knackered oil....its burnt components in the bear box.....which can cost thousands....serious bummer since I've only had the car for 3 weeks or so. Do you know if the dealer holds any liability? I believe my warranty says that if the defect was present at time of sale then its not covered as they would expect the dealer to have inspected these parts prior. Dealing with dealers and waranty companies is like I'll let yo'll know. In the mean time I think all Auto owners should check their ATF since it can be a very exoensive item.

Syed Shah Posted April 21, 2004 Share Posted April 21, 2004 Time for a built auto Don't try to repair this one, and I would not even bother changing the fluid to try and help, it sounds seriously shot, a used one or a built one is the only way forward. Not sure if the dealer will help in any way, dpends how good they are. But worth a try. Did they service it before you got it? Link to comment Share on other sites More sharing options...
SUPRA FLY Posted April 21, 2004 Author Share Posted April 21, 2004 Maaaaaaaaaaaaan am not getting any good news at all :( What makes you say its seriously shot mate? Hove you experienced somin like this? What is it likely to be? the TC, GB or both? Yeah it was serviced 2K miles ago and the dealer apparently carriedout a detailed inspection on arrival ofthe car and prior to selling it. Link to comment Share on other sites More sharing options...
