Whats the number on the side of the 4L60E mean?

[setzer6127]

Hi guys,

I'm doing a 4L60E swap and the tranny in my car has a big 35 on the side of it next to where it says L60E,

The one i ebay'ed has a 34 next to 4L60E,

Now i already know that the bell housings are alittle different, my original has a bolt top dead center, the new one doesnt, and the shifting shaft out the side is about 2" longer on the new one...

So i'm guessing i'll need to change the shifting shafts, but should i switch the bellhousings? the dealer service manules i have for my 98 doesnt show a top dead center bolt in the diagram either...

So.. after a lot of mumbling, does the new one pose a problem seems as it doesnt have the same numbers? or do i just need to make the changes i just mentioned and i'll be fine?

Or should i try and sell the rebuilt i bought on craigs list for what i paid and just take my original in and have it rebuilt?:think:

I would suggest you get one from someone who knows what to send you, And if your a 98 camaro you have a bolt dead center top FYI
