Hello! I own a 1999 Subaru Outback that has developed what appears to be a transmission slip problem. When I am driving along, and have a need to accelerate (often while going up a grade/hill) the engine revs up, and slams into gear. And I mean slams. It often causes a jerk in the steering wheel, and today the tires broke traction (i.e. chirpped) when I was going up a hill, and had to accelerate. I have taken it to a dealer and they could not get it to happen and I also took it to a local mechanic who could not repeat the "slip". It does seem to be more prevelent when cold.

 

Does anyone have any ideas? Thanks in advance.

Sounds like the seals in the tranny are going. I used to have this problem on a nissan. It would buck like crazy through most of the gears untill it was up to temp and then it would stop. I took it to my local AAMCO (friend owned it) and he told me it needed what was called a "banner" service. He did mine for free but they usually cost about $1,200.00 You might want to try to replace your filter and fluid before going the repair route. When adding new tranny fluid be sure to add an additive like Lucas tranny to it.

 

Go from there.

Thanks for the response. I changed the fluid, but have not replaced the filter. The good thing is I did buy the extended warranty, and it is still covered so I just want to get the problem fixed before the extended waranty expires.
