my 95 s-10 blazer is very sluggish at high speeds around 80 mph. It feels like the trans is slipping or so. it also does it if I am traviling about 40mph then i pass some one it starts it. but if i start at a dead stop and floor it it accelerates like normal. does any one have an idea what is going on with the trans.

When was the last time you had the transmission fluid flushed out and a new filter installed? How many miles are on your truck?

i just bought the blazer last week, so i dont know. there are 119,000 miles.

Brada, What is this a 4x2 or 4x4 drive axle?

two wheel drive

First thing I would do is have the trans flushed out and a new filter put in, About $100 bux, from a good trans shop...

ok i will try that tomorrow thanks

What you are seeing is quite normal, at 40mph and 80mph, the tranny is in overdrive which lowers engine rpms for fuel economy.

No engine is snappy all throughout the engine rpm band.

The computer will have the transmission going to Overdrive whenever it can.

ok thanks blazerLT

I just checked my Trans fluid and the fluid on the stick as like some type of orange chunks on it. What do make of this?

Orange chunks on it?

CAN YOU TAKES PICTURES FOR US? We need to see this.

Chances are your radiator is defective allowing coolant into you transmission cooler which is part of the rad.

Don't drive it liek this or you will be fixing a US$1500 tranny in addition to a rad replacement.

Honestly, don't drive it until it is fixed.

let me see if i can get a pic of it.

sorry its telling me that my picture is to big to post.

resize the photo or go take the photo at a lower resolution.

Ah, you have the rusty tranny dipstick tube problem.

Those are rust flakes. I have them on mine too. Just makre sure you get the tube replaced or at least get your filter and fluid replaced sometime soon.

shouldn't he replace the dipstick too? hopefully prevent contamination? or not a huge deal?

Yea, he should if he wants to.

GM has released a revised dipstick that has a better seal that stops moisture from entering the tube.

But I heard this is one hell of an expensive repair though.

I am not to concerned about this seeing I check my tranny fluid every 3 months or so and the rust is very insignificant and won't get sucked into the tranny seeing the filter will stop it.

Just best to change the filter and ALL the fluid.

I just changed my fluid and this tranny is shifting like a dream again.

I suggest going to Jiffy Lube and getting the tranny fluid changed through one of the machines and THEN go to a shop to change the filter and pan fluid.

That way you have a clean slate.

thanks guys for all the help i will get my trans cleaned out on Sunday. hope it helps. thanks

Hey 95blazerFD,
Let us know the outcome after the trans flush and filter.
