Thanks for the work boys, Great episode! Glad you found the shudder issue, you said it was only going to get worse so I’m stoked we have addressed this while the trans is out! There’s a lot going on in there, definitely not a DIY job that one! 😅 Thanks so much, wouldn’t trust anyone else to build the trans 🔥 Bring on the extream valve body and billet converter, power for years to come 👌

[@RoamLyfe]

Hell yeah!! Keen to watch this 🔥🔥

[@user-yy6tc5js4i]

Would love to see a A442f tear down!

[@brianroberts3575]

Thanks Rod and James, great info video, enjoy watching these strip down, rebuilds episodes.

[@yamumatittys]

It’s amazing how many parts are in am auto it blows my mind, in a manual bloke but autos are awesome for hard wheeling.

[@frankspinella250]

Great episode Rod…good to see you fellas getting trained up by you…at least we know your knowledge is going to the next generation.

[@danoflatz7]

Brilliant episode, hopefully see an A442f tear down soon.

[@Br3no94]

Great episode! Appreciate the detailed break down! Would love to see a V5AWF/A750F tear down!

[@coreydavis5552]

Well done boys would love to see you rebuild one as well

[@twinshock175]

This was a very informative video, I was interested in this part of Toms build also. You explained the guts and the glory of that box. I am interested in the Nomad valve block. Will be looking for one sometime in the future.

[@my98wagonoid]

Hi Guys, Really enjoy the technical videos. Can you please do a video on modifying the a442f.

[@WholesaleAutomatics]

Yes we will do so.

[@darcykeddell4930]

yes im very interested for a cast pan for my re4, a trans cooler kit made for a gu would be awesome too

[@user-pj1uj8mo1m]

Looking into getting a tougher Re4 to go behind the 4.5 litre Cummins I’ve just ordered from diesel conversions Australia…. I’ll be on the phone to these guys first thing in the morning to order my new box!!!! Great video lads 🍻

[@michaelwalkley2765]

Hell yea. Also thanks for the plushie toy patrol that you sent me guys. I love it haha

[@WholesaleAutomatics]

Our pleasure!

[@doitwithdave1161]

Dam boys, that was so nice. Nissan Patrol all the way. Thanks for the brake down. 👍

[@WholesaleAutomatics]

Our pleasure!

[@chooky5684]

Loved this 1 and when yas say it got warm how warm is to warm??

[@MntlMajorkozmo]

Owner of a 93 gq with the auto. The state of this box sounds like my one. Any idea how many kays are allegedly on it? Planning a few power adders later and will definitely be looking at a valve body upgrade at least.

[@bikerssupportingcountrytow6904]

James congratulations in making a change in life including marriage and what I've seen in hurt so far you will go a long way in life so keep up the good work and don't let rocket take the shit out of you just give it back he loves it. DOZA @ BIKERS SUPPORTING COUNTRY TOWNS Pittsworth QLD Australia

Thanks boys, great viewing 😎 Show us a Spanish D40 5 speed if you have any 👍🏻

[@Ckktopa]

awesome

[@linus0189]

Greet video guys. How do you diagnose if it’s a third gear shudder or a lock up shudder?

[@MattysWorkshop]

Gday, another awesome informative video, you said you make the components yourself, have you guys got a machine shop as well or contracted out?, throughly enjoyed watching, cheers

[@WholesaleAutomatics]

Both, but mostly contracted out to local companies.

[@chrisdawes6081]

Interested in new deep pan

[@michaelconnors5339]

I'll subscribe so I don't miss the A750f tear down video when you do one.

[@SAVCBF.]

Good info, I've got the 180mm bell housing. There's a buzzing noise coming from my auto, im guessing it might be one of the solinoids on the valve body.

[@WholesaleAutomatics]

Replace the oil filter first and see what this does. Solenoids wont normally buzz in the GU Patrol. A restricted oil filter will cause a little cavitation.

[@Overthetop254]

What would usually make it hold 2nd and not change to third after box gets up to temp , I have replace valve body oil wasn’t burnt and there was minimal metal around the magnet

[@WholesaleAutomatics]

When you say you changed the valve body did you mean the complete valve body assembly including lead frame and solenoids?

[@adamhunt318]

Great vid was wondering I just bought a tb48 with 5 speed to do a bit of off roading and camping if the motor is kept stock and kept light weight should be a pretty reliable gearbox for the application thanks

[@WholesaleAutomatics]

Yes it will be fine but if you are going to tow then heavy duty Nomad valve body and deep cast pan. Here is the link: automatictransmission.com.au/select-your-vehicle/nissan/patrol/gu-4-8l-i6-petrol-with-5-speed-auto/?make=Nissan&model=Patrol&series=GU%204.8L%20Petrol%20with%205%20Speed%20Auto

[@adamhunt318]

@@WholesaleAutomatics yeh no towing just camping and 4wd the only concern is going down hill in low range manual mode runs away do I need some sort of lock up kit or maybe reduction gears in transfer case not sure which I need though the brakes work a treat but don’t want to rely on them any help would be much appreciated

[@user-lu5ov9wf8p]

Awesome rundown guys. I’ve got a rattling noise that starts when I get into 3rd or 4th gear, won’t go away until I drop back down to 1st or second along with a decent clunk as it gets into gear. Any ideas on where to start looking? Cheers!

[@WholesaleAutomatics]

Give Trevor a call on 03-97628004 and he will be able to help you with this one.

[@mgbgtcarguy5411]

Thanks for an interesting video. I have a GU4 with auto. I have had mixed advice about towing a medium sized caravan with overdrive. What are your thoughts? Is a trans cooler advised?

[@WholesaleAutomatics]

Nomad Valve Body and Dual cooler would be the perfect upgrade for the Nissan auto when towing, here is a link so you have have a look: automatictransmission.com.au/select-your-vehicle/nissan/patrol/gu-3-0l-turbo-diesel-with-4-speed-auto-2/?make=Nissan&model=Patrol&series=GU%203.0L%20Turbo%20Diesel%20with%204%20Speed%20Auto

Love these videos. Can we do a dumb ass video on how Lock up works? Keep up the good work

[@WholesaleAutomatics]

Yes, we have a couple already: kzbin.info/www/bejne/sKW2kKOmZ7SXfM0

[@rickr33]

I'm about to fit an re4 behind my m57 powered gu patrol, should I waste my time trying to get the factory TCM working as the car is originally manual or go straight to a compushift?

[@WholesaleAutomatics]

Oh, that’s easy, Compushift every time! Solves every problem and is fully adjustable via an App on your phone. We have sold about 2,000 of them over time and they are simply brilliant.

[@jacksonhutton6895]

Why does my re4 take a bit longer to shift from park to drive. Will shift to L and 2 fine revs out till it gose donk and its fine. 100m down the road its good.

[@WholesaleAutomatics]

Check oil level first and if fine then service auto replacing oil filter. See what you find. Both 1st and 2nd are boasted pressure but drive isn't. If it still does it after the service then you could be looking at a forward clutch problem.

[@cheyenneindiestarkey3126]

Hi Guy's, I'm looking for advice on the repairs/work needed for our Transmission. The Transmission operates fine when the car is first started (All gears can engage while the RPM drops) and then after 10 to 20 seconds the Gears disengage and the RPM rises again, the vehicle won't move. The Transmission has been overhauled with new Gaskets, Seals, Friction Plates etc. I have air tested the Clutch Packs and Pistons and all works as they should with pressurized air, the Valve Body has been overhauled with new gaskets, seals and the Solenoids have been Ohms tested with the correct specs, I've run power through the Solenoids and all are opening and closing as they should. I have not replaced any of the Solenoids (only cleaned and tested). I need some advice on where to go next or what could possibly be going wrong with the above mentioned symptoms. I've tried to call you's but haven't been able to get through, any advice would be appreciated thank you. James

[@WholesaleAutomatics]

Sound like you have a blocked filter, even if you have just rebuilt, remove filter and check. If it is blocked what has blocked the filter so fast? Super common but you would not think so after rebuild but check anyway.

[@cheyenneindiestarkey3126]
