hey guys

i got a v35 (g35) in Australia and i have a 8 speed cvvt triptronic gearbox.

After scraping my car on curbs, the transmission oil started to leak and then my car decided not to change into gear when i drive. it works some times and then when i stop and go, it will stay on 1st gear. By then i would do a u turn and go home then WALLA it works!

i got the oil problem fix and spent 4k AUD doing it, then after 1 week it happened again and its been 3 days and i havent drove it.

i warm it up for 15 mins to see if it made a difference.. no result

now that dude wants to charge me 3k to open up the gear box and have a good look, the thing is... g35s are new in Australia and he admitted to himself that he knows nothing about the car....

i cant find any gear boxes like mine and was thinking can i just put in a normal auto gear box? i doubt it tho..

PLEASE GUYS HELP ME

 

Don't know if we US guys are going to be much help. We don't have that tranny over here.

Sounds like you may have to open it up...

 

$4k is one hell of a "curb scrape". Sounds like they did more that just re-fill it...

Oil leaking out of an automatic will cause a couple of different problems - inability to shift / hold gears and overheating. The first is easy to fix just by filling it back up with the correct fluid while the second can cause permanent damage.

* Make sure your transmission has the right fluid level.
* Toroidal CVTs do not use typical transmission fluids, so make sure you are filled with the right stuff.

Swapping yours out for a typical 5AT is not likely to work. While the new trans will "fit in the hole", modern ECUs and TCUs are so strongly linked that they don't play well with others.
