pete.osborne69 Posted January 5, 2016 Share Posted January 5, 2016 Hi, I have recently replaced the oil filter for the auto box and upgraded from a stock rad to a Whifbitz one which needs a separate autobox oil cooler (also fitted) filled up the fluid (as per repair manual) and I'm now having some issues. When I'm in Drive the gear seems to "slip" out of gear and into neutral and then back again after a few seconds (doesn't seem to be a set time frame) this normally happens when I am sat in a queue or slowing down to a halt. I have checked for error codes and I get nothing. Anybody any ideas Thanks Quote Link to comment Share on other sites More sharing options...
David P Posted January 5, 2016 Share Posted January 5, 2016 (edited) This can be caused by a failing odo, the pink wire mod should fix that? http://www.mkivsupra.net/vbb/showthread.php?72588-Code-42-Fix&highlight=pink+wire+mod Edited January 5, 2016 by David P (see edit history) Quote Link to comment Share on other sites More sharing options...

David P Posted January 5, 2016 Share Posted January 5, 2016 That's it, I've just posted up the same link. Quote Link to comment Share on other sites More sharing options...
pete.osborne69 Posted January 5, 2016 Author Share Posted January 5, 2016 I've been reading through the thread and I don't get any of the other issues or error codes that others have posed and my odo seems to work fine would this be worth trying or is it possible it could be something else Quote Link to comment Share on other sites More sharing options...
David P Posted January 5, 2016 Share Posted January 5, 2016 Without any error codes showing, it's the likeliest problem, assuming that the TPS sensor is adjusted correctly? Quote Link to comment Share on other sites More sharing options...
pete.osborne69 Posted January 5, 2016 Author Share Posted January 5, 2016 How would I know if that is adjusted correctly as I've had that part off for mirror polishing and just fitted it like it came off Quote Link to comment Share on other sites More sharing options...
pete.osborne69 Posted January 5, 2016 Author Share Posted January 5, 2016 Never mind I'm just reading your post now about the J-Spec and adjustment Quote Link to comment Share on other sites More sharing options...
pete.osborne69 Posted January 5, 2016 Author Share Posted January 5, 2016 So I have read and looked at http://www.mkivsupra.net/vbb/showthread.php?t=207697 and tbh I don't get what the Japanese manual part is saying Quote Link to comment Share on other sites More sharing options...
GTR Fever Posted January 5, 2016 Share Posted January 5, 2016 It sounds like you are low on transmission fluid. Remember you will need more oil than standard since you are running an external oil cooler. Check the fluid level properly to be sure. From my past experience, it takes just less than a quart of oil extra to fill the trans cooler (I'm running a Mishimoto external transmission oil cooler) Quote Link to comment Share on other sites More sharing options...
David P Posted January 5, 2016 Share Posted January 5, 2016 (edited) If the ATF is not up to correct level that could be the problem. The TPS requires accurate setting or it could be causing the problem. Neither of the above will show a fault code. You have found the Japanese Workshop Manual which has the correct settings, the English version Manual has incorrect values. Search around and you'll find the English WS Manual version for instruction and use the Jap Manual values. Stick a feeler gauge of given size under an un-tampered with throttle stop and check for continuity on/off position between the top two terminals on TPS and nip up the screws. If you have dicked with the throttle stop too, you will have lost the datum point and be in the land of guess measurey.

pete.osborne69 Posted January 5, 2016 Author Share Posted January 5, 2016 Thanks I will have a look in the morning when it is lighter, meanwhile is it safe to drive as is or will it damage the autobox? Quote Link to comment Share on other sites More sharing options...
David P Posted January 5, 2016 Share Posted January 5, 2016 (edited) Around the block if you like, around the county if you like Russian roulette, at least check the dipstick! Edited January 6, 2016 by David P (see edit history) Quote Link to comment Share on other sites More sharing options...
pete.osborne69 Posted January 5, 2016 Author Share Posted January 5, 2016 Thought so, I'll have a look when I get back from work in the morning until then I think I will leave it parked up in the drive Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted January 5, 2016 Share Posted January 5, 2016 Don't forget to check it on a flat surface with the engine running Quote Link to comment Share on other sites More sharing options...
pete.osborne69 Posted January 5, 2016 Author Share Posted January 5, 2016 How long would you recommend to leave the engine running? I know in the manual it says till the oil is at a certain temp but I don't have anything to measure it with Quote Link to comment Share on other sites More sharing options...
David P Posted January 5, 2016 Share Posted January 5, 2016 The dipstick has both cold and hot level marks. The engine coolant temp gauge will be measure enough. Quote Link to comment Share on other sites More sharing options...
pete.osborne69 Posted January 5, 2016 Author Share Posted January 5, 2016 Thanks and my bad I miss read the manual I read it as the oil should be at 70-80° and level at cold instead of use cold as a rough reference when the engine does not run Or drive the car until it reaches operating temp 70-80° Thanks I'm glad you mentioned it otherwise I would have done it wrong. So if I drive to work (aprox. 2.6miles) it should be at operating temp giving me an accurate reading where I can check the oil level and adjust the tps sensor if required Quote Link to comment Share on other sites More sharing options...
trebor69 Posted January 5, 2016 Share Posted January 5, 2016 My new supra was doing something similar to this but since I refreshed the solder on the odo it's fine. Quote Link to comment Share on other sites More sharing options...
GTR Fever Posted January 6, 2016 Share Posted January 6, 2016 it sounds like your transmission was giving a small slip which is why I suggested the oil level. Especially after my experience doing the same thing like an idiot lol Quote Link to comment Share on other sites More sharing options...
GTR Fever Posted January 6, 2016 Share Posted January 6, 2016 oh and you can check it when cold as well. What I do is usually with two people but one person could work. Start engine and select gears R, D, 2, 1, N, R, D then back to N before checking the oil level. This allows all the valves/ solenoids to open and fill with oil before getting the level.

David P Posted January 6, 2016 Share Posted January 6, 2016 Auto box problems are mostly self inflicted by poor maintenance, electrickery dickery and/or throttle-body tinkerings. Quote Link to comment Share on other sites More sharing options...
pete.osborne69 Posted January 6, 2016 Author Share Posted January 6, 2016 Okay so I checked the oil level at work and had to top it up engine was at operating temp when I did this can't say I had noticed it happen after this. But that being said it stopped for a while the other night when the car was at operating temp but the problem came back when the car had cooled down. I also selected every gear Inc. Park before checking the oil just went a basic up and down gearbox. If the problem persists I will use the gear pattern as stated above and then check oil level again. I am going to have to do this on Friday morning when I get time but in the meantime it looks like I'll have to walk to work and back Quote Link to comment Share on other sites More sharing options...
David P Posted January 6, 2016 Share Posted January 6, 2016 More secrets. One litre below level is enough to stop it working properly. How much fluid did it take to top up? Quote Link to comment Share on other sites More sharing options...
