Do you know who makes this kit and where it can be purchased? I have a GMC with this trans and I have heard nothing but bad things about it. My trans is OK so far but if it dies I would rather spend the money on a Turbo 350 rather than re-build a trans which is most likely to just die again. Jim

I saw the same problem on a Chrysler car, it turned out to be that the tranny oil cooler in the radiator was broke and antifreeze was getting into the tranny explaining the extra fluid. The tranny eventually went out after suddenly locking up! I recommend to have the radiator check and cleaned let them know of a possible leak to the tranny.
Response:
Just a thought. If the fluid smells like burnt wires and you have driven the truck with the tranny slipping for any amount of time chances are the clutches in that tranny are pretty bad. How much is a warrenteed junkyard tranny ? How much are you spending on fluids and pan gaskets ? How much do you like your truck? – Hide quoted text — Show quoted text – > Can’t aswer all but the burnt tranny fluid never left the tranny .About 9 > quarts i beleave stay in the torque converter. >Hi, > My 1983 Chevy K-10 has a 700R-4 tranny that likes to burn ATF.

Their is a kit to replace the 700R4 with the THM 350. I comes with a spacer for the rear of the 350 to make it the same length as the 700 and a special output shaft to mate it to the transfer case. Cost is around $100.00 No drive line changes required. With oversoize tires the overdrive is not as important as it is with a stock truck. Would not be my choice but the option is out there.

I didn’t think junkyards gave warranties on anything. I really wouldn’t buy anything from a junkyard as they are all run by hillbillies in these parts… I’ve seen ‘em get a tranny out of a car… They flip the car over on it’s roof and use a torch to cut it out from under the car. I only stick to simple things like fenders and lights, etc… I could always run to the parts store and buy one… Anyone have any experience with these tranny’s? The ones you buy from places like Advance Auto, Pep Boyz, etc.? Keith – Hide quoted text — Show quoted text – > Just a thought.

Hi, My 1983 Chevy K-10 has a 700R-4 tranny that likes to burn ATF. It has an external cooler that sits in front of the radiator, as well as using the cooler built into the radiator. I noticed the tranny slipping slightly when I just started the truck. The slippage went away as the truck warmed up. I checked the fluid and noticed it was too full and burnt. I took the pan down and noticed some flakes of metal in the pan. After putting the pan back on, and refilling the tranny to the proper level, I noticed it was still burnt looking, although it had more of a red tint than before (probably the ATF in the cooler made it like that ?)… What could be causing this? What do I need to do? Is there some kind of flush or additive I need to add to the tranny? The guy I bought the truck from put a 3/4 ton front and rear end under it from his K-20, could this be the cause of it? Should I just try changing the fluid again in a couple of weeks to see if I can get the fluid to look/smell less burnt? I heard the 700R-4 wasn’t really a very good tranny, could I change it out with a Turbo 350 tranny without a lot of modification? What tranny would bolt-in in it’s place? Sorry for so many questions… Keith

Response:
You might as well try a tranny flush. For what it costs, it MIGHT help. At the tranny shop, they can also help with your answers. Talk to your buds to find a reputable one where you live.
