n2ota2 is right because I was an idiot and shifted my 4l60 in my 93, in about 4 months i destroyed my tranny, now swapping to a 6spd bottom line leave your stock tranny in D learn from other peoples mistakes, Im an example.

 

Hey Frank or any of you tranny pros....since I don't know dookie about a tranny rebuild, what do I need to do to beef up my 4L60E tranny? I have about 108K on it and right now I have it tuned for firmer shifts. I'm thinking of going a lil more aggressive by doing a valve body shift kit. I have a B&M shift Improvement kit laying around but thinking of Transgo Kit instead. I was told to go with TCI internals for a rebuild if I want it to be stronger. So a rebuild consists of the clutch plates, band and filter? I'm probably missing other items but anyhow...Im not seeing any rebuild kits in Jegs or any of my motor mags. All I see is TH & C4-6 series of rebuilds. If theres a 4L60E kit I can purchase from an online vendor, any of you guys please shoot me in the right direction.. I'm trying to get as much use out this tranny as I can & semi-hard shifts...if it helps any...I'm doing the Hotcam next month so I guess I don't need anything agressive but I plan on doing some heavy pedal a bit. I'm still not sure about a converter yet bcuz I'm hoping I can get away with a rebuild and a shift kit..but I was suggested I use a 9' TCI lockup. I forget if a 2600 or 2800 was mentioned. Well, thanks..in advance...btw..car will ever hit track..just my quick weekend grocery getter...

thanks..late

If any of you think that manually shifting your trans messed it up, your very mistaken. I'm sure there were other issues that caused the trans failure.

manualy upshifting no but manualy down shifting will uterly destory it.
