I've moved on.

Apparently not

Maybe I've missed the whole point here, but is it possible to replace the early 2001 transmission with a used 2002/2003, make sure the software upgrades are done and be done with it? Is the TCM the same?

I'm fortunate here in Melbourne as there is a Volvo salvage yard that also do the mechanical work; if it fails within the warranty period THEY need to foot the bill for replacement labour. Experience has taught me this is the best possible solution rather than DIY or hiring an independant garage.

2002 yes, 2003 no. At least not on US spec cars. I can't get a definitive answer why other than the fact that the electronics are different.

Hi people, sorry for bump thread but I must

First let me introduce my self, Dejan and I'm here because of google and problem of my good friend, sorry on my language if i miss or bad spell something is not my native language

Like you probable know my friend have 2001 S60 T5 FWD and his geartronic gear box is start to make trouble, is about 150000 miles and "dealer" say that got TCM-002C >(5th. gear incorrect gear ratio) and TCM-002F>(lockup function;slipping or not engaged) ... What that can be , what is worn or wrong ?
First service who know to fix this is from us about 300 miles and start price is 450$, dealer have only option of new and it's about 5300$ .
Can anybody say maybe what we can do to not throw money on new oil, software update or is just because that trouble?
Thanks

P.S. Gearbox is AW 55-50SN

UPDATE:

Finally found a used transmission out of a donor V70 and hot damn it's working again.

Took a full year to find the transmission and have it swapped out.

Car runs/drives well for now.

Car is for sale.

I was googling "Volvo skips third gear" and came up with this thread.

My venerable 2002 XC70 survived the valve body rebuild and gave great shifts for two weeks then about 30 miles into a leisurely Sunday drive decided to drop 3rd gear from its reportoire.

I duly removed the valve body, fully inspected and disassembled it and received the same result.

I now placed ANOTHER valve body in the car from an '01 XC (which happened to share transmission numbers) and again got the same result.

I didn't touch the BAND ANCHOR bolt though I feel that the B4 piston which acts directly on the 3rd gear band anchor is somehow at fault or the band anchor has disintegrated.....possible??

I'm going to try to view the band anchor through the B4 piston port to see if it has rotated or released.....I have a transmission on the bench which I can get reference from.

There are so many missing 3rd gear posts on the internet and not one of them has a happy thread ending

Hi precopster,
Sounds like the same issue I'm having with my v70.
Basically no 3rd.
Transmission shifts fine from 1-2, then revs endlessly before clunking into 4th.
Going up hills is not fun at all.

I have read up about the B4 servo cover and seems like a good thing to try.
That and a fluid change (not flush) and a software update.

It's not so much the B4 cover I'm keen on viewing.

Behind the cover is a piston whose pointed end leads to the 3rd gear band. It hydraulically pushes on the band which then activates the 3rd gear function by means of a braking action via friction material on an internal drum.

When the drum stops rotating 3rd gear is activated.

Lack of third gear can be one of three problems (or more??) :

1) Either the band has shifted away from home position (possible bolt removal or simple dislodgement)
2) Hydraulic actuation of the B4 piston has failed (air pocket??) or seals on the B4 piston surround are damaged
3) The valve body circuit designed to provide hydraulic flow to the B4 piston has failed or has a blockage

My aim is to remove the B4 piston this weekend and test the bore to see if there is smooth interface b/w the piston and the bore. If there is a lack of smooth action the bore may be damaged or a contaminant has lodged itself inside the bore. Many of the failures of 3rd gear reported on forums seem to be occurring shortly after fluid change even when the band anchor bolt hasn't been disturbed.

Shot this video this morning on SLS, SLT and SLU connector location and testing.

I have TCM-0113 code which is a Pressure solenoid SLS signal missing.

I read an open circuit across the SLS solenoid. Broken loom or connector not plugged in??? I'll find out soon.

I have no 3rd gear which is caused no doubt by the SLS (line pressure) problem

Thanks for sharing mike!
Big job hey!
My car is sitting on jacks right now as I have to replace the front subframe.
I will be having a look at the transmission while It's up to get an idea of it all.
I'm also ordering a VICE VIDA software and cable so I can do some error coding.
