No, I'm not talking about a 13-year-old Malaysian hooker I picked up =P

My buddy has got a 1997 Chevy s10 pickup and when he goes to shift it into the Drive gear, it slips when accelerating and instead has to use 1st or 2nd gear constantly, with the 3rd gear also doing the same slip.

He has no check engine light and says the problem's about a year old.

What's the best course of action for diagnosing the problem?

 

bump, I the aforementioned friend, I just joined this forum. Help Please...

Pull the tranny dipstick tube and smeel the fluid, does it smell burnt. If so your tranny is toast.
Is the fluid red or dark in color? Red = good, dark= bad.

 

Thanks

 

Thanks, I'll check it in the morning

 

i have the same problem, is there a quick fix for this, or only a rebuild?

 

Fix depends on teh problem.
Check the fuse.
Most tranny problems are not in the tranny, typically its an engine performance problem, or a sensor problem.

 

Well, I checked it, the fluid is okay. I haven't tried to drive it in "D" since last year (I was using 2, my auto trans has P R N D 3 2 1). I recently had to replace the water pump and the v-belt. Now that it doesn't overheat, I tried driving in "D" and it works mostly, it just slips a little.

I really hope this minor slippage isn't severe enough for a rebuild. I hope a quick fix would help. I was thinking about getting a trans flush, but I dont know if thats the answer....also, if a band is slipping, does that require a rebuild...

 

slipping is a problem no matter how small.

flush/fluid change will never fix a tranny problem.

Having said that, replace a qaurt of tranny fluid iwth a quart of Lucas Tranny treatment. It will help the gaskets/seals survive a little longer. Plus it may seal off a small leak which will reduce/eliminate(maybe) the slip.
