I have noticed a little whine while in a lower gear until it shifts to 3rd. I know when my 70 chevy pickups torque convertor went out it started doing this same thing. THis sucks. It seems like it has been getting louder and louder by the day.

I have been having TC trouble too. I keep getting P0741 codes after the transmission temp gets above 220. I will usually pull over and let the temp come doan and use my Scan Gauge to clear the code, and it will lock up again. I'm looking around for a stronger replacement TC so I take care of this problem before I get stranded somewhere.

I just found this converter:

700R4/4L60E Edge Heavy Duty 12" Lockup 1985&UP (Non LS1) : https://www.700r4l60e.com/store/product.php?productid=281&cat=59&page=1

Would this work with our transmission?

This TC is 1 inch bigger than our OEM TC, which means less stall, less torque, probally less heat as well. Our truck's TC is orginally 11 inches with a 1600 stall. If you put this tc on an TBSS they will gain a 2800 stall on their truck so depending on which tc you put on the stall will vary based on the engine.

The smaller the tc the more torque, heat and power you'll get. The tc i have is 9.5 inches and has a 3600 stall (normally for V8 and tbss trucks). But since i have an I6 the 3600 stall declinded probally to around 3200 which is still enough power for me.:thumbsup:

I think i'm leaning more toward the Hughes unit. I just can't find any dimensions on it.

Would it fit our flexplate and everything else? Could it be just drop the old one and throw the new one in?

if it uses the same transmission as ours then yes it should fit

Hughes says its for a 1999-up 4L60E:

Summit Racing has this in the description:

- Torque Converter, Heady Duty Towing, 1,800 RPM Stall, Chevy, 4L60/4L60E/700R4, Lockup, 30-Spline

I don't really see any other reason why it wouldn't work... Guess I have another part to add to the list! :thumbsup:
Then it should fit. Let us know when you get it installed.
