It is sorta a given that your trans/diff will need to be replaced soon if you have "spirted" driving habbits, part of the problem with owning a high hp/torque car especially FWD.


dont get me wrong the 4t60ehds are far from weak but are no TH400.

Eitherway it is the "weakest link" on these cars...something you should budget in to the cost of ownership IMO.


if the wheel is shaking I would look at a possible failed balljoint..thats what happened when mine failed.

I have heard bad stories about jiffy lube in regards to trans flushes (ie leaving it 1 quart low or overfilled) but it probably depends on the store. Part of changing the fluid is changing the filter usually.

good news! i replaced the tranny fluid and filter yesterday and totally cleaned out the underside of the transmission...wow, lets just say there was soo much metal shavings and goop that i didnt even realize there was a magnet in the bottom of the pan...i seriously thought my car didnt have one...but, everything has been cleaned and reassembled...i managed to get ATF for $1.79 a quart from NAPA and a filter with a new seal for like $18.95...major deals...

the trans is running very smooth now and the only noise im hearing now is from my bad wheel bearing when i take corners, and yes, that is my next top priority...thanks for the help guys and does anyone know where i can get some of that friction stuff for the clutches?

FYI, to clear up some questions here:

INTENSE doesn't sell any clutches or parts for the 4T60E. They only support the 4T65E.

A couple. DrJay and I have both found and used good professional rebuilders for the most bullet-proof builds we've seen so far on the 60. Every single part you can think of for the 65 is available for the 60. Including shift kits.

yeah i know...i was pissed when i found out ive got a 4T60E instead of a 65...oh well...i guess ill survive...
