Which oil do I use for my 5 speed 4 cyl isuzu tranny?
80/90 gear oil or normal pink tranny oil?
Another question is how do I know how much to add?
From what I was told, I add the oil where the speedo sensor is.
Any help would be great!!!
Thanks Andrew

I HIGHLY suggest using ACDELCO Syncromesh. I have tried the Royal Ourple Synthetic and a week later went back to Syncromesh (hope I am spelling this correctly)..lol.

I am sure you can do a search on Pennocks on how much is required, for my 4 speed I need about 4 lt.

Hope this helps..Oh, add a little Lucas would help also, depending on the shape of your tranny

5w30 or GM Syncromesh. If you put 80w90 in your trans, you might as well hand the keys to someone else and just let them have it. As you won't have a car regardless. 80w90 will destroy the trans.

As for where you fill it, yes you fill it from the speedo hole.
