Volvo: gearbox..a slipping clutch would be on a manual transmission

Resolved Question:

I have a Volvo XC 90 2003 model with I am told a GM4T65ev-GT gearbox on a 2.9 engine it is losing drive similar to a slipping clutch would be on a manual transmission, is this more likely to be a gearbox issue than an electronic one

Expert:  Enes replied 4 years ago.

that problem on xc90 6 cylinder is bad gearbox they to many problems with gear boxes you need to check for fault codes it is possible that you can fix the problem with software update to the ecu but most the time gearbox is bad the xc90 new gearboxes are much better when you replace it

 

ask if you have more questions

Customer: replied 4 years ago.
I think it is to simplistic to say that it is a bad gear box, I understand that the gear box is a manual with an electronic change system and a clutch drive, I cannot see how the gear box can slip, are there exploded diagrams of the this drive system available to see just what method of torque converter drives this box
Expert:  Enes replied 4 years ago.

i understand you if you can give the fault codes from the scanner im sure when you use the advanced scanner on the transmission it will tell me more what is going on .

why it slips the clutches on transmission get worn out like on manual transmission or the springs and bands inside trans just don't hold and car will slip also one thing that also takes out that trans is coolant leak from radiator small amounts off coolant mix oil in trans thru the radiator and when they mix it takes out trans out , also on left wheel if you take out the center bolt for the axle is behind the Volvo center cap on the wheel if you get oil leaking out that you axle has failed and the grease mixed with trans oil taking trans out also , what you have on your car regular gm transmission is not Volvo gm made it for Volvo but with very poor results

 

let me know what else you like to know i can send you only picture of transmission and connecting parts

Customer: replied 4 years ago.
The oils are ok this has been checked, if you have pictures of the transmission set ut I would appreciate having them however I need to know what type of drive system i.e. hard clutch or fluid torque converter. I do not have the fault codes available
Expert:  Enes replied 4 years ago.
