Auto Trans Question What trans is in a 98 auto corvette? Pretty sure I remember seeing 4L60E or 4L80E on the casing...
And how hard are they to rebuild? What kind of tools is involved?
Car im working on was cruisin and a couple quarts of atf leaked out only while cruising on a highway at a steady speed, put a couple quarts back in but not enough to get it to the bottom of the hole (but gotta be very close) and when you press the gas it slips....Think it's fried or it's just low on atf?
Thanks

As far as rebuilding them it is a fairly intense process that does require special tools. It has a 4L60E with the Corvette Servo installed. A couple of quarts leaking out on the ground during a drive is pretty severe. Do you know where its leaking out from? Hole in the pan? Cooling line cut?
4L60-E AUTOMATIC TRANSAXLE FLUID CHECKING PROCEDURE
Start the engine and allow the engine to idle until the transmission fluid normal operating temperature has been reached.
Depress the brake pedal and move the shift lever through the gear ranges, pausing a few seconds in each range. Return the shift lever to the PARK range.
Raise the vehicle on a hoist. The vehicle must be level, with the engine running and the shift lever in the PARK range. CAUTION: The engine must be running when the transmission fluid fill plug is removed, or excessive fluid loss will occur. Transmission fluid may be hot. Since the actual fluid level is unknown, stand clear when removing the fill plug. Have a container ready to capture any lost fluid. Do not turn the engine off with the fill plug removed, as you can be injured by hot transmission fluid being expelled out of the oil fill opening.
Remove the transmission plug. IMPORTANT: The transmission fluid may darken with normal use and does not always indicate contamination or oxidation.
Check the fluid level. The fluid level should be even with the bottom of the threaded plug hole.
Add DEXRON III automatic transmission fluid in increments of 0.5 L until the fluid drains from the plug hole.

Thats the GM checking procedure. Looks like a big pain in the ***
