DIY - changing your transmission fluid/oil, M/T 7afe Options

[Batman722]

I changed the transmission fluid/oil in my 7afe recently and Manny (presure2) took some pics - thanks Manny
I was having some slight grinding going into 2nd gear in higher RPMs and I figured changing the tranny fluid would be a great idea. Since it has been changed, no more grinding

tools needed : ratchet, 24mm socket, 3-4qts transmission fluid/oil, oil drain pan, jack/stands
time : 30min - 1hr, depending on your mechanical skill level

DO NOT attempt this when engine is hot, wait until the engine is very cool/cold.


first you need to loosen this bolt (fill plug) with a ratchet and the 24mm socket

bolt removed


it is located here, it is facing the front of the car. The transmission is circled in yellow and the arrow is pointing to the bolt location

the bolts are usually very tight and could be difficult to loosen

next, jack up the front of the car (putting it on jack stands is always safer) and with the 24mm socket you need to loosen this bolt (drain plug)

Remove drain plug. The drain plug is located directly under the transmission. You may need to remove some of the plastic under the engine for easier access. Be sure to put the oil drain pan under the bolt when removing because the old fluid/oil will be pouring out.

now after the old oil has drained out (10 min later), replace the drain plug - make sure it is secure - and lower the car.

My personal choice
Pennzoil Synchromesh


pour 3-4qrts of the Synchromesh into the fill plug hole (you might want to use a long funnel or pour/squeeze from the bottle into the hole) until full - it will start pouring back out. I used just less than 3qrts



Once full, replace fill plug - make sure it is secure - and wipe up the excess that has spilt.

Done.

Notes :
- be sure to dispose of old fluid/oil properly
- according to the BGB - 7a transmission refill = 3.5qrts, 5s transmission refill = 2.6qrts
- this procedure should be the same/similar for both 7afe and 5sfe

As a fact the shear stability of the ATF in use was more than adequate for use on the lubrication standpoint, and the addative package contains almost the same amounts of sulphated ash and zinc.

Really and honestly it helped alot while it was in use. It went from a 3K shift with grindage, to a 4+ shift.


I changed to the syncromesh last night, and no more grindage at all!! mad props to whoever was pouring out the money to try and fix this problem. I found it at the local Autozone for $6.59 a quart, and it was well worth the cost.

Just a side note about it, it is alot thinner (lighter in oil weight) than the 75W90 that is reccomended for use in the transmission, but it works GREAT!!
