safari awd trans problem

safari awd trans problem

Postby larrydrop [OP] » August 26th 2008, 3:45am

Hi,
Any diagnosis help on this would be greatly appreciated. I have a 2000 safari awd with 119K miles that suddenly developed a trans problem today.
The vehicle has been driving fine until today. The van had been driven earlier and was warm. When pulling away from a stop sign the van bucked a couple times and then ceased to engage in drive. My wife said there was no real grinding noted, just acted like in neutral. She was able to drive it home in 2nd gear. On testing this evening, no gear will engage in either drive or 3rd. When shifted into 1st it will engage with a small clunk, then pull off normally. If manually shifted up it will shift fine into 2nd, 3rd, and 4th, once rpms are high enough. The trans will deliver power but will slip out of gear if in 3rd or 4th and rpms drop. Also, when pulling away from a stop in first and second if the wheel is turned while accelerating there is a noticeable growl. One last bit of info, but possibly unrelated, is the tendency to feel what seems like a slip then engage when starting from a stop, engine cold, and wheels turned sharply...I figure this is a transfer case issue but bring it up just in case...it has been intermittently doing this for several months.

Thanks in advance!

The forward sprag has piled up.
This requires removal of the trans for repair. The good news is, that there will be no other damage from this-the metal shavings are contained within the sprag.

And just to clarify, a spag is a one way clutch. It transfers power in one direction, and freewheels in the other. Yours is now freewheeling in both directions. That is why you can get all the gears when shifting manually.

Thanks for the diagnosis! In your opinion would it be ok to use this vehicle for a short trip (about 30 miles) and pulling a pop-up camper? I'd like to get some use out of the van this labor day weekend before laying it up for repairs. Will I be putting undue stress on another component of the trans? What do you think are the odds of something else going wrong?
best regards,

If at all possible, don't use the van-esp. for towing a trailer. Since a major"holding" component has failed, it will put a lot of stress on everything else.

Sorry for the bad news.
