Aston2jz Posted July 6, 2013 Share Posted July 6, 2013 I've been having problems with my supe, for the past couple weeks maybe but has got alot worse this week. (JSPEC 93 AUTO NA) This has happened at the worst possible time, insurance and tax due amongst other things so I need some help please to narrow the problem area down so I can get it fixed as quickly as possible without costing a bomb doing the old trial and error. ... It started off as when I am pulling away from standstill or in low gears up to 25mph I'll push the throttle as normal to accelerate but get no response so I'll push it further to try accelerate and the revs build up past 3/4k but the speed doesn't increase, then 5 seconds later all of a sudden there will be a judder it'll feel as if it just catches on to the revs and engages gear. The car feels completely normal at higher speeds 40mph+, it's just at lower speeds it feels like it's kind of slipping, at first i thought the back wheels were spinning and couldnt get traction. I'm currently driving with the manual gears which feel more responsive and better but it still slips. I'll try get a video posted, and pics also if required. Thanks.

keron Posted July 6, 2013 Share Posted July 6, 2013 Have you checked the fluid level? Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted July 6, 2013 Share Posted July 6, 2013 Have you checked the fluid level? With the engine running? Quote Link to comment Share on other sites More sharing options...
Aston2jz Posted July 6, 2013 Author Share Posted July 6, 2013 Ok I had checked the oil hot, level ground, ran through the gears and in parked and it read fine. Honestly I forgot to leave it running whilst checking, i checked again under the same circumstances but with the engine running. The fluid level dropped by half, way below maximum, oops my bad lol. Topped it up with 1.5L dex3 but still seems like its playing up, maybe the damage has been done using overdrive hardly makes any difference now.

There is a guide on here somewhere, probably in FAQ I would think, that details the correct way to check your fluid. But basically, handbrake on and wheels chocked to be sure, engine ticking over and run through the gears and then return to 'D' with the engine still running and then check it. Your original post described classic low fluid symptoms. Good luck. Where in Beds are you? Quote Link to comment Share on other sites More sharing options...
Aston2jz Posted July 7, 2013 Author Share Posted July 7, 2013 I'm in Dunstable, thanks guys anyway but I think its permanently damaged now, still isn't catching on the gears if I push the pedal down more than an inch at once after filling the oil. How much do autoboxes generally go for these days? guess I'll need a torque converter too and anything else? Quote Link to comment Share on other sites More sharing options...

mihai Posted July 8, 2013 Share Posted July 8, 2013 does oil leak somewhere? It will cost you more the transmission oil and filter than the gearbox. If does not leak you just need a good service to the auto box, oil, gasket, fiter. I had the same problem on a single and here i am now 4 months later trying too sort my manual conversion:( Quote Link to comment Share on other sites More sharing options...
Aston2jz Posted July 8, 2013 Author Share Posted July 8, 2013 Nope oils levels fine, the box is completely gone now, can hardly even drive it 10ft lol. Just so strange how it happened so suddenly and within 3 days rapidly escalated. Will get back to you Keron for the autobox Quote Link to comment Share on other sites More sharing options...

Will get back to you Keron for the autobox Once it goes slightly bad the filter gets clogged of the slight debris in the box, clogged filter means no fluid to the rest of the parts causing everything to burn out.

Yeah makes sense. Can I change the autobox with a new one without having to remove the engine? or can anyone link me to any guides please?

Kaan W Posted July 8, 2013 Share Posted July 8, 2013 No need to remove the engine, but its not that hard really. Basically undo torque converter bolts, then prop flange nuts and slide prop off, undo gear linkage and electricals, cooler pipes, top 2 gearbox bolts, starter bolts, then the rest and it should slide off.
