Re: 2001 5-speed automatic transmission & problems - start here

Post by tomvv11 » Thu Jan 19, 2017 11:17 pm

So to clarify an earlier post, if I want to replace the AW55-50 in my 2002 XC70, I can NOT use one out of a 2003-2007? Anyone know why not? TCM/transmission incompatible? Does my TCM stay with my car or would the TCM follow along with a replacement tranny?
I did 3 complete flushes in about 40,000 miles, now have 166K. At 158K after latest flush, had an indie shop do the drive adaptation. They said my SW was as updated as it could be. That improved the revvvv-SLAM! during 3/2 and 2/1 downshifts about 90%. But now it's coming back and I would like to slay the beast once and for all. Has anyone had their valve body replaced/rebuilt by a shop? Trying to avoid a complete tranny swap unless I could get a lower mileage later model without built-in time bombs.
I can usually fool the tranny into not slamming by waiting a moment then feathering the gas on real gently after coming around a corner, but if I have to think that much about shifting I'd rather have a stick shift.

I see that it's been done on Swedespeed though I can't recall if the guy brought the TCM over with the transmission. Once you have the old one out and the new one side by side you'll be able to identify what the differences are in wiring. The looms coming out of the valve body can be swapped over quite easily.

A while ago I did a massive parts search on my 2001 XC70 (late build) and found that Valve body part numbers run through to 2002 XC70s & differ on 2003 and upwards however I found some matches in LATER model years: viewtopic.php?f=9&t=54590&start=30

Have 02 awd 2.4t seeing some shift harshnees, and stop neutral harshness.
Did flush, seems better, also tried this procedure.
seemed to help a lot, a little tedious.

Service. The TCM can sometimes take many miles to fully adapt. If you do not have access to the factory tester or Volvo VADIS, then you might try the following.

1. Drive the car forward in the “D” range at about 5 mph (8kph) and bring to a gentle stop. Repeat this procedure at least 10 times.
2. With the engine at idle and your foot on the brake, shift from “N” to “D”. Wait for about 30 seconds. Release the brake. Repeat this procedure for 10 cycles.

If the above does not cure the fault, you will need to get access to a factory tester to reset the adaptation. Remember though that the TCM is constantly updating so not every shift will be the same.

I don't think the UK fix will resolve your problem.

It is my thought you have sticky solenoids that need to be rebuilt or replaced. It is possible you have actual valve body wear, but without pulling it apart it is tough to tell.

Were it me I would pull just the valve body and rebuild it with the TransGo kit for your transmission. It is not difficult. It worked for me.

If you are afraid to do this - you can just pull the solenoids and rebuild them with the TransGo kit and ignore all the other parts or buy new/rebuilt solenoids - swapping out on the solenoids - the valve body can be left in the car. Easiest and fastest approach.

Every valve body will have either no stamping on one of the plates (meaning it is a first generation) or a letter A, B, C ... Each letter tells you it is a newer version than the prior one - as AW made improvements. For a like for like valve body swap you need to get the same letter valve body. It is unclear from my research whether a newer letter valve body, with the newest software and a fresh adaptation will work on a prior lettered valve body. My theory is it will as Volvo only sells the newest lettered versions - but that is my theory. I would just go for like for like to be safe.

Not sure if this makes sense.

I tried the UK fix a week ago and used full synthetic fluid. I used Gibbons method and 12L of fluid.

I had already fitted the Transgo kit about 4 years earlier however after about 6 months the car (XC 70 2002). started to produce P0705 almost every week and sometimes twice a week.

After fluid counter reset and adaptation reset (no drive cycle as per the UK post). it started off with bad flaring 2-3 and 3-4 for the first 30-50kms and some harsh 1-2 shifts.

I've only done about 200kms since the above work but so far no codes and shift quality is good.

Precopster - When you did your original rebuild did you do the Adaptation and Fluid Reset? How was the fluid you just pulled out?

Also - doesn't the Fluid Reset by default also do the Adaptation? I thought I read that some where or saw it when I did it a few years back.

Fluid reset and adaptation reset are separate commands within Vida not together. They can operate from the same window one beneath the other when choosing adaptation reset. If you want to do fluid reset by itself it's in a separate window.

Yes I did the fluid/adapt and drive cycle 4 years ago but I could hardly get the triangle to light as it was all over the place. Perhaps the whole problem all along was fluid quality. I used synthetic Mohican JWS-3309 initially.

Fluid was filthy even though it had only done 30,000kms. These transmissions with over 200,000 miles without a fluid change history will continue to contaminate the clean fluid because the filters take 100% of the fluid flow and if the filter is already clogged...........

We bought the car at 180Kmiles with little to no transmission service history and now has 201k miles.

I've been wrestling with a flu for a week now and had zero driving time to see if it continues to code.

Admittedly the first 3 sump drops were drain and fill 4 years ago not through the cooler ports so perhaps this was the best treatment this car has ever had.

Continues to impress after 500kms. Shifts are softer/slushier and no codes.
