Re: 3rd and 4th gear are not engaging + weird smell

oab_au: thank you for confirming.

I have already talked with some carshops, so i have basic idea of overhaul cost...

The thing is, i have to use SVX anyway, say 50 Km a week. I drive very gently, not letting it much over 3500rpms - if i would not know car is 4 speed, i would not say its broken - so i hope it will be the solenoid...

svxcess: thank you very much for all informations you posted ! I really appreciate it !

Problem is , that i have called to 4 carshops, including Subaru and only AT oriented shop and none of them measuring line pressure ...

What is most funny is, that guy from last shop i called, told me, they do measuring line pressure, but do not have adapter for sizes of 90s Subarus socket...

So, its not ideal, but i am forced to simply buy that solenoid A, change it myself and see if it make differcence or not.

Is this correct part number of SOLENOID A : 16102AA020 ?

https://parts.subaru.com/p/Subaru__/...6102AA020.html

Only in short, where it is located and how hard it is to change it, is there DIY somewhere ?

Thank you very much guys and take care

Filip

Filip,

you must accept that repair shops are not interested in locating a problem when they can pursuade prospective customers to spend big money on a complete transmission rebuild and this fact has been the undoing of the SVX throughout its history.

Common sense dictates that the cause off a problem must be located before a repair is attempted. In this case it is logical to suspect a lack of line pressure, however this must be proven before proceeding with work which could be in the wrong direction thus waisting energy, time and importantly money.

The "A" solenoid can be replaced by dropping the transmission oil pane and removing the valve body, but although much simpler than removing the complete transmission, quite a lot of work is involved. Having done so you still can not be absolutely sure that you are going to fix your problem. Surely it makes sense to first locate what is causing the problem and. then proceed knowing what you are doing.

You can make up a pressure gauge in less time than it will take you to remove the oil pan, much. less the valve body. I will come back with when I locate instructions which I have previously written up.

I note that you are using the car, but carefully. I trust and presume that you are not getting any sort of smell, as this would indicate that clutches are slipping and can detect if any slip is occurring while you drive. Otherwise you will be wearing things out and a complete rebuild will become essential. :-(

Meantime do't panic. LOL

------ Refer previous post.------

Filip,

Refer attachment regarding making up a pressure Gauge.

You mention a repair shop which has a gauge but no fitting for the SVX. This information should enable them to adapt something.

Re: 3rd and 4th gear are not engaging + weird smell

Hello Trevor,

what you saying about repair shops is definitely interesting - idea that whole SVX "bad tranny" phenomenon, is in fact due to lack of informations on owners side and shops being too sly and fake on the other side, is something worth to think about...

Thank you for your attachment ! If i understand it correctly, you gave me instructions how to create pressure gauge. From brief look, it looks it won´t be as much complicated to build, as one would think.

Definitely better option, than buying prematurely solenoid. Thank you !


And yeah, so far i have been calm

Filip

Filip,

I have found some additional details illustrated in the workshop manuals which help yo find the pressure gauge connection port and also provides information covering the direct testing of clutch pressures. You will be able see how useful the pressure gauge will be in diagnosing your problem. Click/Go here and scroll though the complete data and in particular note illustration fig. 113 :-

I hope this helps,

Cheers, Trevor.

Re: 3rd and 4th gear are not engaging + weird smell

Trevor,

this manual is absolutely perfect news, thank you ! I have been looking for something like this around whole internet, including here. Without success, until now.

As i mentioned in my first post, my english is not perfect, so just to be double sure, i rather ask you about attachment you posted last time

Apart from 40mm(2,5 inch)gauge with over-pressure tolerance of 160psi, i am supposed to buy just brass fittings and thin plastic tubing, in order to make working pressure gauge ? Am i right, if i assuming that, that brass fitting is supposed to be plugged into test plug location ?

Thank you,
Filip

Re: 3rd and 4th gear are not engaging + weird smell

Greetings Filip,

The short answer is YES --- and as I have said previously, your English is very good. By contrast I am a dim-whit as I have only one language! LOL

Please go back to my previous post dated 3 October and take some time studying the attachment which provides detailed instructions. Any type of pressure gauge will do, as long as it covers the pressure range required. It need not be the exact gauge I have suggested. You can use any sort of flexible tubing as long as it will take the pressure involved. Simply apply the common sense, which you obviously have.

The forum is providing you with some good practice in corresponding in English and congratulations, you are showing that you are at the top of the class and I hope I am providing you with some ongoing practice by not simplifying my words.

If you are not sure of anything, in any way, do not hesitate to ask, as I will be pleased and happy to provide further information.

Cheers, Trevor.
