I will be ordering my solenoids soon, and will put them in myself, after that I will post the results......... stay tuned everyone.

 

Oh well everyone, here are my results.
1.I bought the 'Transco AW55-50 shift Kit on ebay for $99.00 bucks
2.I bought a 'Vida dice' from china almost $200 plus shipping (best invest I made)
3.Rebult SLU,SLS,SLT solenoids Grinded the rear and cleaned with drill bits.
4.All solenoids were tested as recommended. However the SLU and the S4 are Jammed in the off position. I believe the SLU is jammed because of the spring. the S4 is just bad. After I put the Transmission back together, I did a Vida Dice read and found out that the two solenoids in question have a bad power reading.
I had flaring, hard shifting. After doing a rebuilt and vida oil and transmission reset. all of the problems are gone except for the jamming of the two solenoid, which are causing a slight rough shift from 1st to 2nd gear.
My recommendation is to buy all new solenoids, SLU, SLT,SLS, including all of the S1-S5. The solenoids in this Valve body are no good, if you are going to do a Job like this one, I suggest a complete valve body, or a complete solenoid replacement, and a Vida Dice. This is a complicated valve body, just because it seems to be running right, it probably has a lot of hidden volvo transmission codes in the Vida Dice scan reader. This car has a computer running almost everything, one computer failure can cause a failure in another. When dealing with the XC70 I suggest you get a VIDA DICE, It will tell you what you are getting into.

 

I forgot to mentioned that you can by all the solenoids @cobratransmission.com

 

I bought this kit, and it did fix some of my problems. I suggest you get new solenoids. The repair kit will not fix your solenoids if they are bad, even if your solenoids pass the ohm test, this does not garrantee that they will work under pressure. Get new solenoids!!!!!!!!!!!!!!!

 

The shift kit did correct some of my symptoms, I had flaring, and a bang when it flared up between gears. The shift kit comes with a new updated sleeve to stop the bang, it worked. However, like i said in the previous posting, the kit did not fix bad solenoids, the kit can only fix good solenoids that are having pulsating problems due to debris keeping the pental from proper movement. You do not want to repeat this process again, it is a lot of work, fix it right the first time. Depending on your symptons you might only need the three linear solenoids (SLT, SLU. SLS). But I suggest a full rebuilt, because flaring is also caused by bad sleeves in the valve body when they become worn and can not prevent fluid from passing through.

 

I hate to burst anyone's bubble. But you will have to re-machine the valve body if one or more of the end plugs become worn and can no longer plug the bore, therefore causing transmission fluid to pass through. Sonnax makes a special tool for this.

Like I said before folks, Just because you put in some selonoids does not mean that it will work, it's a fifty/fifty shot. Have the valve body examined or buy another one that has been truly rebuilt, with all selonoids replaced and all valve bores properly examined and pressure tested.

 

For those of you that are having Issues with your Volvo XC70 Transmission. Here are a few things Myself and others here have done to solve their issues.

Is your XC 70 slipping, flaring, or a bang in between gears? I have emailed a few Volvo mechanics to help with this Thread.
First check your fluid, look for the tell-tell signs like the color of the fluid or metal particles.Since this transmission do not have a easy accessible filter, you might want to consider an external filter (check with your mechanic). The fluid would be dirty, if not changed at the proper intervals, This condition will also clog your solenoids causing them to malfuction. You might be able to solve your shifting problems with just a fluid change. However, you are looking at a 50/50 chance of success. Volvo has also had a issue with the Netural Safety feature of this transmission, you will have to go to a Volvo dealer or buy your own 'Vida dice' and remove this feature in your TCM by a Software update.

I personally have a 2001 XC70 that I love, When I first Got it, I had a issue with the ABS module. I found a posting about the bad factory soldering on the Pin connector, and yes that was one of my problems. I re-solder those pins and my ABS and Brake warning lights no longer displayed. But I also found out that I had other issues. My Valve body solenoids were no good, I bought a Linear Solenoid repair kit ($99 on ebay) I followed the instructions and even look at a video on 'youtube' to get futher instructions. In short, the kit corrected some of my issues like a bang between gears, and it even reduced the flaring, however it didn't fix the problem. I then ordered a 'Volvo Vida dice' from china, After a vida dice read, I began to see my problems. The selonoids I rebuilt even after doing the ohm test, were no good. The 'Vida dice' showed those selonoids as a bad reading, and the SLU solenoid was shut open. Even the S4 solenoid was showing a shut open on the 'vida dice'.

You might solve your problems with just replacing the three Linear Solenoids (SLU, SLT, SLS) it's a 50/50 chance. I suggest a complete valve body rebuild with all the solenoids replaced. You can search online or you can buy all your parts either on ebay, or @ cobratransmission.com

There have been other suggestions regarding the change of your B4 servo, this to might also help. But remember, whatever work you do, you will have to re-learn this Transmission. You can either search online to re-learn your transmission, or you could email me, I will provide those instructions freely. Maybe someone here could post them.

YOU DO NOT WANT TO DO THIS JOB TWICE! YOU HAVE TO LOWER THE SUB-FRAME TO GET TO THE VALVE BODY ON THIS TRANSMISSION. IT IS NOT A CHEAP OR EASY JOB. GET IT RIGHT THE FIRST TIME!!!!!!!!!!!!!!
