1995 Jeep Cherokee question

Dan:
A whining can be many things so I can't give you a definite answer. Is it shifting, slipping... Is the fluid burnt?

its not slipping and it shifts into gears fine it just wont go over 50 and it whines while in park and u dont hear as much noise while driving its a grand cherokee laredo ive tried to find trannys but no luck

The noise may be coming from the converter. However, if the trans doesn't slip and it shifts properly, are you sure the engine isn't causing the 50MPH limit?

the exhaust sounds a little funny like a whistle or like a turbo would sound like because it gets to 50 fast but then cant get any faster the tranny shifts good i would say almost like its gonna hesitate without the jerking

I want you to check something. Everything you have described sounds like the catylatic converter is plugged. I will kill engine power. Check for back pressure from the exhaust. Listen for whisteling or ratteling from the converter area. Also, if you can, disconnect it to see if it runs any better.

I can't be sure, but now that you described the turbo like sound, that is what I'm thinking. I can't think of anything in the trans that would stop you at 50mph. Especially if it is shifting good, not slipping...

Let me know.

their is very little pressure from the tail pipe the exhaust is new as well

Is the converter new? There should be a good bit of back pressure.

yes the converter is new but back pressure is very little the muffler is new as well the exhaust is about 1 3/4 diameter doesnt look like two inch at all the whine seems to come out of the exhaust i think thats where it sounds like its coming from
