No problem, it's not too late, and I just seen where these seals are.
Anyway, I will see if it will be inside the rebuild kit I had order @ autotransparts.

Some parts came today from rockauto (order sunday, and here today!)



I have an other question :



@ Left the old, @ right the new transaxle input speed sensor (ISS) from STANDARD # SC 127
I see few difference... It's terrible, or right ?
You know, I had chang all the other sensor & solenoid. And because the transmission is open, I prefer chang this too..!

There IS an early/late turbine(input) speed sensor for that. The difference is whether or not it has a "boss" on the bottom that fits into a hole in the case. If the new sensor fits, it will work. Also, there is a metal guard/shield on that harness(as shown in your pic).Those are different for the two styles of sensors, also, so be sure to check that they are both exactly the same. One word of caution...double-check the wire colors AT the connector on the new sensor. SOME are not wired properly, and the two wires are switched. Just be sure the new sensor has the same wire color in the same location in the connector. The green wire has to go in the same position as it is in the old sensor connector. If they are swapped, the sensor will NOT function, and you'll be pulling the trans back out...

The two seals for the channel should be in your kit. There are also two different sizes of the larger seal. Be sure to carefully match it up. The kit will have both sizes.

And, of course, check the green wire & black wire...

There are two ways to fix the problem, studs or inserts.

For a stud kit see: http://www.northstarperformance.com/sgstuds.php
For timesert inserts see: http://www.timesert.com/html/gm.html

If it ain't broke, don't fix it. ...unless you really don't like pulling motors.

How about the main filter, in the side cover? I don't see one. The two small filters in the bottom pan can be cleaned and reused, but the main filter in the side cover should be replaced.

Also, you'll notice that there are 2-3 different lower valve body gaskets(plates) in the kit. These are the gaskets that are metal. IF you change that gasket/plate, be SURE to use the proper replacement from the kit. The gaskets are stamped with a number, on the bare metal "dog leg" of the plate. Your original plate will also have a stamped number. Just match the new with the old.
