Transgo And The Track

[180 wanabe]

Thought I would post up my thoughts from my last track day on Wednesday @ the QR sprints

Previously every track day I have been to in my V35 I have always left the car in D mode with the PWR button pressed as the triptronic mode was far too laggy to be of any use

I recently had the transgo shift kit installed and was interested to see what sort of a difference it would make

I found that there were some pros and cons when it comes to trying to get your quickest time with the shift kit fitted compared to stock

The kit was good in the fact that I could drive the car like a manual in triprtonic mode and actually benefit from some sort of engine braking + the shifts happened for the most part in triptronic mode when I wanted them to unlike how the auto box behaves when its stock

I also managed to shave .16 off my best lap time however the improvement is somewhat on the small side that it could be attributed to a number of factors other than the shift kit

The negative, although I considered it more fun than negative was that the harder/faster shifts turned the car into a powerslide machine if I wasn't careful or more so if I wanted it to when shifting from 2nd to 3rd. This was with 245 Toyo R888 semi slicks on the back not so good for lap times however

I'm half keen to take the car to a Friday night drift session with some stocko 17's on the back given how easy it was to slide with the semi slicks on

Don't forget I am running an LSD unlike 99.999% of the other auto V35s out there

Luckily I had AWD, it loved the track, for about 2 laps before the trans went into overheating limp mode.

I don't think I would take a stock valve bodied car to the track though, the clutches would slip badly imo, causing more heat. Do you have a large trans cooler?

[180 wanabe]

Have never been in limp mode cars been to 9 or so track days with around 20+ laps a day

Do run a trans cooler, dont think you would call it big but you can see the size in the pic + I run the best bang for buck cooling mod by removing the grill at the track so the car gets max airflow even tho it causes more drag

Also note that my tranny is going to be dealing with a lot less power than yours given you make double the power I do!!!

Hey you keep saying this.......but every coupe that I have done a Transgo kit with in Sydney has had an LSD. Infact I am pretty sure it is standard equipment on manual or auto. The only difference being that the manual runs a 3.538 diff ratio and the auto runs a 3.327(or something).

Who said that the auto's don't come with LSD?

[LineItUp]

Well my 6mt doesn't have an LSD.... stupid brake lsd...

id be interested to know what the transgo is like for daily suties? I.e ido a lot of stop start driving, does it thunk between 1st and 2nd with little throttle?

[scotty nm35]

With the RE5 the line pressure is variable, meaning at light throttle is shifts silky smooth but when you plant it the shifts are firm. Definitely great for daily duties but it needs to be installed as per instructions, something professional transmission repairers seem to have a problem with.

The trans can be a little clunky compared to normal, not all the time just the occasional harder shift at light throttle or sometimes when dropping it back a gear. Nothing to worry about though. The clutches will last much longer without the drawn out slop into gear the factory valve body has.

Which suburb are you in Norby?

mine isnt transgo brand (its custom made), and it does hit second quite hard regardless of throttle position. but this is in a 4 speed...

[scotty nm35]

Custom made means it has some locally wound springs shoved in the place of the stock ones. This does not = shift kit. Yes it bumps up the line pressure but... Transgo have obviously spent a lot of research dollars sorting these kits out, replacing various pistons, adding valves and upgrading springs, all of which gives it the perfect crisp shift imo. I'm certainly glad my transmission specialist didn't cheap out and manufacture his own parts.

im in Croydon North, im actually considering doing this mod. Just realised today the paint on my bonnet has been repainted and is all now peeling... if it isnt one thing its another with this f***ing car... i still love it though

Pretty sure MV Automatics are a bit more detailed than that

I was sure I had found something about the diff specs of different V35 cars a couple years back. I know that the old diff in my car was crap and constantly peg legged at the drags/lit up the inside wheel when going around a corner at the track

If you can find an auto v35 that can throw down 2 black lines at the same time with the stock diff ill take my hat off to it who knows maybe a factory option, either way viscous sucks balls

[SMOKEYV35]

copy pasted this from another forum:

2003 sedans didn't have an option for VLSD

2004-2006 sedans had a sport package option which came with VLSD

2007 sport sedans have VLSD, base & journey have ABLS

2003-2004 coupes had VSLD if it was a Performance Wheel and Tire package option, which meant 18" wheels auto or manual.

2005-2007 coupes only those with the Sport Suspension Package had VSLD

*The 18" wheel option for 05/06 is only that, wheels and tires

VLSD became part of the Sport Tuned Suspension package for 05/06*

You hope.

I can guarantee they haven't put the same amount of R+D into their valve body upgrades that Transgo have. All I can go by is the local 'specialist' that makes his own springs, they aren't anywhere near as refined and simply bumping the line pressure gives clunky changes. If you are happy thats great but the RE5 is a completely different gearbox...

And a two way doesn't? Give me a new tight oem Viscous lsd any day over a clunky mechanical. (for street)

[Deep Dish V35]

yes i hope and no im not that happy as yet. Hoping their 1000km checkup will involve some adjustment or fine tuning

The diff option list above is for USDM

[scotty nm35]

There is no adjustment as far as I know, they will probably need to take the shims out from behind the line pressure spring in the valve body.

Perhaps a slightly thicker transmission fluid may help slow the clutch actuation down?

Best I can do.

Unless you've got a manual or an auto with 'sport package' then only way you'll know is by jacking it up and throwing it in nuetral.

Open diff's can twin up in a straight line though - my R31 had an open diff, and from a standstill it would light up both - have videos from the drags to show it.

Corners were a different matter though.......single peggers all the way!

I've had cars with open, viscous, 2 way and helical lsds and I'd say the best all rounder is the helical

Nothing puts hairs on your chest like going around a large roundabout in the wet with a nice tight 2 way

[scotty nm35]

I owned a celica twin cam powered KE30 rolla with a migged diff for a few years, you get over it pretty quick, especially in winter. My favorite diff in the wet is the single spinner, no chance of stepping out with spider gears front and rear. AWD FTW.

hey mate just a quick noob question,

when I jacked my car up on a hoist, and in N, the rear right wheel spins by itself, if I put my hand to it and hold it still, the rear left wheel starts spinning,

what sort of diff do I have?

cheers
