Thread: Wow, its still leaking..What next?

Started 1 month ago by Chevy350Sb
I been fooling with this 700R4 for a long time now. I have replaced the front seal, Tcc solenoid, pump bushing, pump gasket, O ring and dipstick gromet. It is leaking from directly behind the TC...it seems to run down the TC and spackle onto the bellhousing untill it begins to drip from the two bottem corners on the bellhousing. I have a spare TC it has the number "6" stamped on it my current TC...

sounds like a crack may be around the converter hub weld or the hub it's self

Just so you know you don't have a flywheel, it's an automatic so you have a flex-plate....

I would be very surprised if that were the cast. The flexplate would have to be broken and you would most likely hear that. If there is a converter shop around you they can pressure test it for you. If you go through the work of pulling it out have it checked. If it is a new reman. converter ask them to check the hub run-out to make sure it isn't beating up your seal. If it checks out OK ...

After replacing all the parts ive named and testing the converter..What else can it possibly be?

msggator replied 1 month ago
The only other thing I can think of is the pump gasket. One of the problems with these forums is you are answering questions blind. I own a converter company and people ask all the time things like what is wrong with the converter or trans because it is doing one thing or another. Sometimes you just have to see it!!!!!!!!!!

Since this is a 700r4 type of trans.... is it possible that the trans is a 27 spline input shaft and you have now installed a 30 spline converter? there would be no power transfer via the input shaft.

Did you have any clearance between the converter & flexplate before tightening the converter bolts? http://www.tciauto.com/Products/TechInfo/FAQ.asp#4 You should feel 3 clicks while rotating & pushing the TC when the Input Shaft splines...
