Hey all, i have notice the auto box behaving a bit odd lately. And by lately, the last month, month and a half or so. :dry:

After i start up, i am on a highway doing 100 in a few minutes. It is holding revs at 2900rpm at 100 klms, then after a certain amount of time, it settles back to 2650 odd where it always has.

On colder days, it seems to take ages to find that final 'gear ratio' for lack of a better word. But when i start her up and get on the highway later on in the day when it has warmed up a bit it settles to 2650rpm quite suddenly.

Is this normal? Has the cold affected anyone else's slush boxes at all? I put a shift kit thru the auto last sat, flushed the fluid etc, but it still seems to do it.

Cheers,

Chris

its the toque converter locking up. is normal so dont worry. doesnt do it suddenly when cold is cos the oil is still thick. the oil thins out wen hot.

So if i flush the lot out and replace with fully synthetic, would that make a difference at all?

When i put the shift kit in, i only drained and replaced with the normal rubbish.

I am planning on an upgraded 3000rpm torque convertor soonish, so i might do it then

My car has done allegedly 64000 KMs, about 7000 KMs ago I serviced my auto tranny with Castrol Transmax Z... meant to be one of the best fully synthetic oils out there for autos.

I know that the oil in question is castrol, not sure what it is exactly. Fingers crossed its this one your refering to lol

      R34 N/a And R34 Turbo (gtt) Transmission.. Uh, Problem.

      By albyz34gt · Posted

      @666DAN sorry to bring you and old thread.     I've got my de+t done and it's all running great other than 1 small issue.    Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd when selected . But nothing when in  drive or what gear your in when you pop it into tiptronic. I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Do ya have any ideas?     Cheers man

      R34 Handbrake light saying ON and intermittently flashing

      By RB25inside · Posted

      Well I recently changed my rear axles and was thinking if I bumped anything, I have been driving the car for a while now though... But it has been raining today so everything is wet under the wheel arches. Brakes feel fine and can't hear any of the metal screamers, I had a squeak coming from one of the handbrake drums but that seems to have gone away a while ago. I was going down a hill when it lit up and I did feel the abs bite for a second and question why it did it?

      ECU sees many times the speed than speedo does (R34 swap)

      By GTSBoy · Posted

      Correct. Um. I dunno. I haven't cared enough about the way that the NA cars work to know for sure. But..... The 33/34 turbo manual cars have an electronic speed sensor in the gearbox that outputs a +/- (ie, sawtooth AC) voltage signal. That is connected to the speedo. The speedo then outputs a 0-5v square wave (ie, PWM) signal that the ECU (and any other CU on the bus) sees. The speed sensor is NOT directly connected to the ECU. So here's the problem. Your new ECU expects to see the PWM signal, but must somehow be getting a direct signal from the diff speed sensor. Which would suggest that the wiring of the NA car is not the same as the turbo cars. I think you will need to spend some time with (hopefully the wiring diagram for the car) and a multimeter to see what is connected to what. Then, presuming I am correct**, you would then want to separate the ECU speed signal input from the rest of the car's wiring, and probably either buy a speed signal converter, or build one using an arduino (or similar). That would take in the speed sensor signal and output a scaled (and suitably rearranged) signal for the ECU. ** We shouldn't presume that I am correct here, because there might be something else crazy going on. I don't think you could convert the speedo to be fed from the gearbox sensor, because the pulse rate from that sensor is probably different to the diff sensor and then the speedo would read wrongly. And this also wouldn't fix the ECU's problem either, because the ECU doesn't want to see the gearbox signal direct either (assuming that they are all on the same wiring, for some odd NA related reason, see above caveat!) Does this help? Probably not. Can you make it work? Almost certainly. With the above work. You should buy a handheld oscilloscope from Aliexpress so that you can view these signals directly. Connect up the probes and drive the car. Show photos of the screen when drving at known speeds and connected to different places, and we'll see what we can learn about it.

      Assuming your brake pads are not worn right down, I'd add a little brake fluid. Is there any sign of a brake fluid leak?

      R34 Handbrake light saying ON and intermittently flashing

      By RB25inside · Posted

      Hello all,  I need of some help. On my drive home my handbrake light lit up and started flashing. When I got home I checked my handbrake sensor under the centre console and nothing seemed out of the ordinary. I have scanned my car via the consult port, no codes shown. Checked my brake fluid as well which is half full. Tried unplugging the brake master but it didn't change anything. Thoughts on what it could be? The master float doesn't seem to be stuck. My car is an 1998 ER34 sedan GT. No hicas but has ABS Photos below 👇🏾
