Only 10,000 miles on tranny and already a problem?
In 3rd. at a stop, when I gave it half throttle it was slipping. Backed off the throttle and tried again, all normal.

Drove around a bit more, no probs. Was I just not fully engaged? or is this how it all starts

 

do you mean the shifter was in 3rd or the tranny was actually in 3rd while stopped?

 

Yeah, shifter in third, at stop.
I drive in 3rd around town to stop tranny seeking.
Felt like it was stuck in 3rd though?

 

Damn 10,000 miles on the SAME tranny . J/K hopefully it just hung up in 3rd, but thats kinda what my last one acted like right before
