Yeah this sucks

Car has 106k miles with orginal tranny(stock converter, no cooler). Trans slips going highway speeds, between 65-80mph. If you put the gas down a little to pass or speed up, it shoots the rpms way up(sometimes past 3000). The weird thing is it shifts fine, shifts great going into overdrive.

So what's wrong with it? Am I due for a total rebuild?

Sprag could be letting go , 106000 in a performance car is getting on up there, What does the fluid look like

Are you sure it's not just the torque converter locking and unlocking over and over again? Maybe your torque converter clutch is going?

Shooting over 3000 if its not dowshifting would be alotta slip for a stock converter

I don't think that's it. Just from the way its acting, it doesn't feel like the torque converter locking and unlocking. The RPMs will shoot up and I'll be holding a steady speed or loosing mph.

Checked the fluid, it looks okay, and no noticble odor. It has been serviced every 30,000 miles(filter and fluid change, not flushed). I did notice if I stuck my nose right up to the dipstick, there was a faint waft of hot tar/fresh asphalt.

Didn't smell anything like the tranny on my Buick when it croaked. That was a smell I'll never forget, and it stunk up the whole car as well. Blew that one up racing my buddy's Pathfinder, probably overheated the sucker.

But at 105k its probably about time for a trans anyway.

I hate to admit it, but you are absolutely right. I'm going to take it to a tranny shop tommorrow(know anybody good in Murfreesboro or Nashville TN?) and let them look at it. Money is tight right now, but I want this fixed right the first time, so expect a call.

Ill look forward to it and hopefully for your sake its something simple maybe this time till moneys better. Good luck anyway

I wasn't sure what his gearing was. Maybe if he had 4.10's or something, cruising at highway speeds, if it unlocked I could see it shooting to 3000.

Aron, when you say the car shoots up to 3,000 rpms when cruising...what is the normal RPM before it shoots up? Does it shoot up 300 rpms, 500 rpms, 1000 rpms?

stock 3.23 gears, so usually 70 is about 2300 rpms.

ChocoTaco369

So when you're cruising at 70 mph at ~2300 rpms and you get the possible slipping problem, it shoots up 700 rpms to 3000 rpms, then back down to 2300 rpms? What rpm does it shoot to roughly? An increase in how much?
