Tranny Slipping? Or is it just the oil?

[P.W.]

I have the semi auto tranny in our 2019 Rt... using Lamonster's oil
I noticed a couple time now when out on a ride the RPM's will rise about a 100 for a second or so....with no change in throttle position....almost sounds like the tranny is slipping. Doesn't do it consistently, just a few times this summer.
Ever hear of this....thoughts?

Thanks for your time and help!!

I got to thinking....last year I used the factory Can Am oil and never had this happen....Now this year with this oil, I'd say this has happened 15-20 times.....Could it be the oil?

Was it slipping on the start of the ride, was the tranny cold?

 

[P.W.]

About 5-6 miles into the ride....my guess

 

[Mikey]

After it warmed up did it slip? I have heard of some slippage going on, when the tranny was not warmed up! I would find it hard to believe that Lamounts oil is the cause, but that's just my thoughts!

 

[P.W.]

I would agree about LaMonsters oil, I'm sure it's good stuff.
It's just odd it never slipped once in 5,000 miles last year (factory oil) and now this year it has with his oil.
Just trying to figure things out.

I would do an oil and filter change back to what you were using before and see what happens. Gonna cost a bit of money, but if the issue clears up you have your answer. If the issue continues you know to research further.

 

[P.W.]

Kind of what I was thinking....Just seeing if anyone else had an issue with slippage, ever.

I just bought lamonsters oil. Haven't changed it yet. Will only be going for a short ride after since it will be going in storage for the winter. I will keep and eye on this next season.

No need to change filter; what little oil remains after a drain in wouldn't fill half a tea cup.

Check your oil pressure. This is exactly what my F3 was doing before the oil pump failed and the engine blew. The HCM is highly dependent on oil pressure to maintain clutch plate pressure.

How do I check oil pressure....take to dealer?

Please don't take this the wrong way but if you are asking the question, the dealer is the answer.

 

[JP58]

You have to remove the oil sending unit that is on the engine and install a pressure gauge. Than you can see what the pressure is while riding and see if there is any loss in pressure at all rpms.

There is nothing in the tranny that can slip..... maybe the clutch?

 

[P.W.]

Wishful thinking it was the oil!
Did an oil Change and took it for a ride today.....Same thing, slips is 6th gear.
Off to the dealer tomorrow to see what they say. I would imagine it's going to be there for quite sometime.
Quick question, is the engine and tranny one unit.... I mean if they end up replacing the tranny would they have replace the whole engine too? Good thing I'm still under warranty for a couple months yet.....but we did opt for the BEST warranty when we bought it new for this reason...

P.W.

 

[JP58]

Yes engine and tranny is all together. It can be fixed if there is a problem.

 

[P.W.]

Okay thanks for the info.!
There is something in the tranny slipping for sure. I just hope the engine isn't being starved for oil pressure too.
I would like think a "idiot" light would come on if the engine oil pressure drops to low..... That's never happened.

 

[Flamewinger]

Just outta curiosity, do you let off the gas when shifting? You shouldn't.

 

[P.W.]

Nope.... always shift under power.
