So not so long ago, i posted a thread about my gt-8's transmission going bad..at least i thought it was the tranny..

The problem went away after an ecu reset and a pedal position relearn.

Just last night the same thing happened again. I was cruising down the freeway doing 100km/h then the it felt like the car's power is cutting out jerking forward and back.

Pulled over, did an ecu reset and off i went again with no problems whatsoever after that.

One thing i noticed though is that whenever i release the accelerator pedal and put the tranny on manual mode, the car would always jump to the third gear. It doesn't matter whether i'm doing 100 or 60 km/h. But if i keep my foot on the pedal when i change the mode it goes to the appropriate gear according to the speed the car's doing.

I've got a feeling that's it's a sensor issue. It's as if the tranny doesn't know how much speed the car is doing when you let go of the accelerator. But which sensor needs checking? How much would they cost to repair?

power cutting out doesn't sound like a transmission problem...hv u taken ur car to nissan to get a diagnostic check for possible fault codes?

i always wait till i get to a complete stop ( at traffic lights) before switching between auto and manual mode...i thought everyone did the same....apparently not ...lol

Haven't really taken any notice about the gaer when i switch to man mode, but I have heard that the five speed box will always go to third, I have 2 mates with M35 stag's and they both go straight to third.

As for changing when stopped it doesn't pose any probs for the box, I would assume that Nissan would have plastered stickers all over and there would have been a note in the manual.

Yeah, i usually change the mode whenever i feel like it. And i've always noticed the gearbox go to the right gear according to my speed. This time it didn't when i let go of the accelerator.

If there is a fault code logged in the ecu wouldn't the check engine light turn on? Man i really need to get my hands on a BlaztII cable.

      While there is no current law for the spoon, let's swap to a different utensil. Example, does the store get fined for selling a butter knife if it ends up being a murder weapon? Perhaps they cpuld be done for assisting if they *knew* it was going to be for such a purpose. But, if used properly, which was its primary design, it's a tool for a job that's legal. I could understand companies being prosecuted if they advertise their products for being road legal if they in fact, are not. Possibly, but not necessarily, the tuners for tuning a car to a non legal fashion(emissions), but there is always the possibility that the customer really doesn't intend to use the car, in that configuration, on the road. So long as the companies can prove they have conveyed how illegal it is to use the now illegal car, in a place where the vehicle must meet the laws, they shouldn't be punished. Not sure about other countries or states, but I've been made aware that I can't legally stop a client from taking and driving their own car in NSW, Australia, even if they owe the shop money. It must go through court to get the funds from the customer, and you need to get the police or roads covering body representatives to come and stop the owner from driving the car, even if I know how hazardous the vehicle is.

      probably around the $1700-1800 fitted in his sizes.  The ar1 is heaps cheaper. Get on scumplace I got some A052 295/35/18 for $400 that had done maybe 20-25 hot laps of SMP.

      People are going faster on CRS than AR1, so there's that 😕

      Go the CRS, cheaper than the A052 and same if not better 1 lap performance when suspension is dialled for it. If wanting to do back to back laps the A052 and can cool off and go again next lap will be the better option. I have gone quicker over 1 lap with CRS than the A050 I came from but may be due to getting more seat time. I am driving CRS on the street lately in different conditions and its going well, a lot better than AR1 in the wet. AR1 is a race tyre, CRS is a Hill Climb/time attack/Sprint tyre. 2 different things, a slick is on the way too. The mighty gay mods choice of tyre is proper rubbish for those that actually drive on track not park at bunnings at night.

      R33 Fuel Tank crack

      Seems to be a common issue, I had a look at two used tanks and both had similar cracks to mine. No one that does plastic welding near me seems to want to do it to a fuel tank lol
