adding auto tranmission additives

[michaelw]

Hi all,

Like most VN's my auto is now so bad that I have to get a good book to read while waiting for it to engage in reverse when cold.
I went and bought some nulon auto fluid additive that claims to fix/help worn seals (a known culprit in the slow gear selection). My question is that as I already have a box filled to the propper mark with transmission fluid and changing it is a pig of a job, can I just empty the extra 300ml of this additive in the top without fear of it doing more harm than good?

Cheers

Mike

it might be best to take it to an auto specialists to get a service on the trans. how long since the trans has had a service? cause it could be changing slowly due to the filter being block and its doing its best to run without destroying itself. if that makes sense

[immortality]

whats the fluid like, pull the dip stick and wipe on a white piece ofpaper, if it's not bright red and clean it needs changing

[bradcad]

I agree. Either take it to a tranny specialist and have a full service performed with a flush through. Can do it yourself if you have a mechanical aptitude, a gregory's and you are patient and clean.

Remember a good fluid doesnt need any additives.

[azkwazere]

The additive is to repair the seals.... which "good fluid" cant fix!

Yes it might be the filter causing the flow issues but im gonna throw in that it just might be your reverse solinode. Check that one out first.

As for adding in the treatment fluid, IF its already full...the auto sump that is, then adding excess fluid may not be such a good idea. What i'd do, drop the auto pan, replace the fluid + filter and add the treatment. Kill a couple of birds in one go.

Hope that helped.

cheers all, I have just changed my fluid about 6 months ago, (tranny wasn't all the great before so it is not my fault) The pennies are a bit tight at the moment, but I'll sling it by a workshop.

How much would you be looking at for a tranny service (4 spd)?

Michael,

Just my experience but I was having trouble with the auto in my V8 VP after 220000 Km and I looked into using the additives in the fluid. I was told they would either fix it or f**k it, and unfortunately in my case it f**ked it. Not long after adding the additives the overrun clutch failed and I lost engine braking. A few months later 4th then 3rd stopped working. As I result I needed a new transmission. Got quoted $2500 for a full rebuild.

On the upside I bought a second T700 as well as some good books and rebuilt my first automatic transmission. It's been in the car now for a few months and is running absolutely magnificently.

CATCH!

Service was around $100 for my trans..... I had similar story to one above, but I only had the car a week, & Im a little rough Anyhoo, I lost 4th & 3rd also, got quoted $1000 for rebuild.

I ended up buying another trans & having them service, shift kit & install it. Cost $765 all up

I was thinking of getting a service, and buying the corvette servo and B & M stage 2 shift kit and getting them to install it. Do you notice a big difference after an auto service? I was hoping to get rid of the clunky downshifting.

[holden007]

Additives are temporal things, do a tranny service and see if metal bits on the magnet (located on the pan).

[NORTI]

I notice the shift kit lol

Cus I got both done at same time hard to say. However I do know that it usually smooths out the changes for a whiles.

If your in adelaide, Id recommend going to DRW, service & shift kit on my VN was around $200-220.

[FadeToBlack]

lol...well yes I already know what a shift kit feels like. I'm assuming you bought the shift kit and had them install it?
I'm in melbourne, can anyone recommend a transmission workshop?

[bradcad]

.....actually additives are a temporary fix. A good fluid will help seals. Nothing is a magic fix, but a good fluid will have additives in it designed to work with the other additives found in dex fluid.

I take mine to Performance Autos in Frankston. They did the service for $110 and replaced a bunch of seals. Cost me last time around $180 all up.

I'm thinking of adding a tranny cooler to further help prevent any possible damage, especially in the warmer months. Is this a good idea?

[cev]

Additives espeically on the VN are just a quick fix, the problem will come back no doubt soon enough.

A Tranny cooler isnt a bad idea as long as ur doing a lot of driving, hard driving especially.

[bradcad]

my (old school) thoughts are tranny coolers are a must. At least get a cheapy from the wreckers in good nic

[holden007]

Where can you get tranny coolers? Supercheap, Repco???

The tranny cooler is quite good for cars with shiftkits which I found when tow heavy. I found holden cooling kits uses the same cooler as B&M and the pricing is simular.
I saw on repco having the pwr cooler and reasonably priced.

[bradcad]

...or if your a cheapass like me hit the wreckers for the genuine cooler (unless your towing 1500kg worth of boat) seems to work well. Just clean her up well, give her a lick of spray can black...beutiful for about $20-$30

Pajero cooler is a nice size...

hey norti i'm in the northen end of adelaide up near elizabeth way and just wondering if you can reccomend a good place
to go for me to get my transmission done... I'got a vp wagon and the automatic transmission is slowly playing up now, took
it to muno para shopping centre and had trouble going from 1st gear to 2nd gear and wouldnt change to 3rd gear.

I got no knowledge on transmissions or motors at all and can do with all the help i can with this problem. Need to find a good
cheap place that can service the transmission for me.. I'm on disability support pension so i'm limited to so much money.

explain to me if that is a good price or is it possible to get it cheaper..
