When flooring it in 1st or from a stop, my trans will rev to red line rather than switching to 2nd, in order to get it to switch i have to let off the gas and let it rev down, this obviously shouldnt be happening, but it only happens in 1st.

So ive had this problem for about 5 months and it slowly got worse, but now its seems to have stop getting worse and it happens around 50% of the time at full throttle, anyone heard of this or know what it may be?

(This is the Auto 5 speed)

Could be an adaptation issue... I'd check the fluid...

This could be a shift solenoid. I'm more familiar with this in other transmissions than the volvo's though.

Get your car scanned, a problem this bad should be leaving codes in the system.
Well sometimes my check engine light comes on, but then it will go off, but im assuming its for the faulty trans.

CEL wouldn't trigger from a trans issue I wouldn't think.

You need to get it scanned with VIDA.

Though this problem only occurs at full or 3/4 throttle, at a regular speed it shifts at the correct RPMs, that part confuses me.

Is the only way I can get it scanned is for me to buy it?

You can have a dealership scan it but they will charge you an exorbitant amount of money. And having your own copy of VIDA is basically a necessity for troubleshooting these cars. Unless you like spending lots of money at dealerships and/or throwing parts at problems.

Could this problem have anything to do with the angle gear? This seems too be a common problem in high mileage R's and mines got 164000 and i haven't had it for long so im not sure what the previous owners have done to keep it upkept

No, the angle gear just transmits torque to the rear wheels, it has nothing to do with how the tranny shifts.
Okay thanks for the info, im not a transmission expert yet:)

Yeah, the AW55 doesn't even know there's an angle gear... I'd say your AW55 is having some issues. You need a VIDA scan.
