trans was opened up today

had a proper oil flush/replace 10,000km ago.... currently the fluid looks like red glitter paint. there is absolutely nothing left of the friction bands. And before you say it, NO i dont do burnouts. This is after normal use (by me). maybe the previous owners were not so kind...

so its in for a complete rebuild plus trans kit. $3000 approx..... and the shift kit is the cheapest bit.

this probably explains why my gearchanges have felt so slow and lethargic. unfortunately it gave no other warning signs, crunches or bangs, it just stopped working.

Not stressed about it. Love the car to bits

factory spec bands, solenoids, etc. just the modified valve body. theyve been recommended as a bit of a nissan specialist who do in-house component mods.

the positive is, its just $1000 more than a replacement USED gearbox.... which i see as the better option

another note: have researched the re4r01b gearboxes, turns out the ones fitted to the VQ motor has different input/output shafts to the RB version, plus the bellhousing..... so you cant assume that all those gearboxes will fit

heres the diagnosis...

upon disassembly, the guys found that the first clutch drum had failed. the friction plates should be retained by a large circlip - that clip had popped out, allowing the friction plates to travel past their correct location and eventually shave themselves down to nothing. this generated extra heat and extra load within the trans. The trans fluid in the pan looked like glitter paint.

The 4 speed auto has only 5 friction plates in there, mine has now been upgraded to the turbo version 7 plate and drum assembly.

the servos have also been discarded and replaced with new larger units from a turbo assembly.

the solenoids have all been replaced for new

the torque converter has been stripped down and rebuilt with all new internals

and lastly, the valve body has had a custom upgrade (not transgo.... apparrently his are better)

all this , including R and R, and a weeks labour.... $3050

The trans guy say this is THE way to upgrade the RE4R01B 4 speed auto box. In my opinion it is too much money to spend on a V35 upgrade unless youve already broken it, however it works out to being only $500ish more than buying and installing a second hand box from a wrecker..... so definitely better for the money.

Will upload a vid to show the improvement next week

under instruction from the trans builder, i am not allowed to use full throttle until after 1000km and a re-check... so here is a short clip of about half throttle from standing start. thanks to my back seat passenger ;)

First to second... is quite grabby. Probably too harsh for my liking... we'll see if it eases up after bedding in...

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
