S80 T6 automatic problem.

Post by LittleMissTitan » Wed Feb 27, 2019 10:09 pm

Firstly hello. First post but many visits here.

I have a 2002 S80 T6 with 4T65EV-GT gearbox.

1st gear no drive.
2nd gear slipping.
3rd up wards ok.
Oil looks and smells ok.

Will not pull away in D or D winter mode, manually select 3rd and you can pull away but obviously slowly and not on a hill.

Ideas to possible problem??

How many miles on your vehicle? Does the transmission behave any differently after it is warmed up or is it always the same? How long has the problem been going on? The 4T65E is a transmission with issues.

See here to see if you can line up your problems (I couldn't)(Also Dave at Triple Edge is a great guy to work with - maybe shoot him an email): http://www.tripleedgeperformance.com/4T ... blems.html

Have you got any codes? As your transmission doesn't match the usual failure problem it could be a failed solenoid or maybe one of the accumulators. Need more information and codes.

Always the same cold or hot.
120,000 miles
The problem literally happened overnight but have driven for prob 500 miles like this with no change.
I have emailed triple edge but no reply (3days ago)
No codes when had it sent to Volvo specialist BUT transmission fault light is now on, sommay we’ll have codes now.
I did try to match symptoms but like you cannot find anyone with this scenario, always appears to be Different pair that fails.

Agree - that is why the codes will be helpful. You could have a solenoid that went bad. It appears possible to test the solenoids from outside with a VOM with the transmission still in the car going through harness. Send me a pm with your email.

I have this current issue. Codes are the pressure solenoid stuck open. My car will drive for about 2 miles then go into neutral. Will not take off in 1, 2 barely moves in 3rd. I did a pan drop with filter change. Ran good for about 75 miles and it happened again. Unfortunately no one in my area works on Volvo transmissions. In the same boat i am. No nownits just sitting in my grass collecting pollen.

It is not a Volvo transmission. It is a General Motors 4T65EV. It is a different configuration then the 4T65EV used in GM cars but, a Transmission specialist versed in GM transmissions should be able to figure it out.

Two points. First as Rick states the transmission is a very slightly modified GM 4T65E transmission. Other than a few hard parts which are larger or slightly different, the rest of the transmission is GM. All of the solenoids are GM. All of the clutch packs save for one are GM. Every major transmission supply source carries the Volvo add kit. If they can work on a front wheel drive Chevy Impala they can work on your transmission. In fact, a few of Volvo's changes were actual updates in the later GM cars.

Second point, to get to the solenoids one has to suspend the engine, pull off a bunch of parts, and then tilt the engine towards the driver side until the valve body cover clears the frame rails. This is exactly what one does for, a Chevy Impala. Of course one call pull the entire transmission if one wants. This can be done with engine by dropping the engine cradle or just dropping the transmission. Exactly like on an Impala, but the parts removed are made by Volvo. The cars are not the same, but the basics are exactly the same.

If I brought in your transmission to 99.9% of the transmission shops at first glance they would say it is a GM 4t65E.

Back on point. To repair your transmission solenoids, if that is in fact what the issue is, one would be better off doing a rebuild while you are at it. It is more work, but only about $250 more in parts. If you do some searches there is a guy in the UK that did the transmission rebuild with the transmission staying in the car by tilting it to do the valve body and then taking off a few more parts to get to the transmission internals. He used, as I used, a video of a guy on the internet doing the same to his Chevy Impala. I did it to my XC90, which is basically the same.

It is not an easy job, but you can ask around for shops that can do a Chevy Impala with a 4t65E, ask if they will rebuild it in car (not likely but there are shops that will do it) and then provide them with the Volvo VIDA steps to access the valve body if they are afraid. It really is the exact same thing. The ATSG manual I used was for GM cars, with a small section that notes the differences. But getting there is the same and any transmission guy or gal will not blink. In car rebuild will be your cheapest route, not optimal, but should work without issue. Otherwise expect to pay about $2500-3000 for a full remove and rebuild.
