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...

    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
    • You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
