As many know I own a 96 SE Bonneville originally owned by my dad and had just over 302k on the car when the original L36 let go. Recently I have pulled the cobwebs off of the car that has been sitting since New Years Day untouched (except for when I moved into my house). I've had an L67 swap on the back burner and am about to start working on it again. I was cleaning out the car yesterday and found my dad'* service records, these were current up to 287k when I got the car. Here'* a great way to spend $17291.30. Things on this car were fixed before they broke with the exception of the tranny, that'* the only thing that left him stranded. All I did to the car was a new set of tires and oil changes and a battery (and a badass system).

damnnnn

so we will see the L67 at SEBF in a month Right???

That is a long service history w/o a doubt. I see only one alternator replacement in 302k, that'* cool. I didn't notice any hub assembly replacements, that'* awesome.

Of course, unless something bad happens, I've been trying to get my truck done first, and I think it will be finished in a week or so

Wow! Only one UIM replacement, averaging over 150k per manifold!! That'* good!

IMO, this is a testiment to why one should perform regular and consistent maintenance and preventive maintenance. Plus it doesn't hurt if you have a real solid car to start with.

Only 4 trans flushes in 302k miles? hmm, i think i know why the trans went out

I don't know what the interval for the 4T-60e is, but I think its like 20k? So that would have been 15 to date? :P

Ah, but its good shes still goin! Keep er on the road!

4 trans flushes is 4 more than I would have given it.

155,000 on my original tranny without a flush yet. IMO, 155K is already a good life span for a 65E. I'm glad I never spent the money to flush it. That'* money saved that I can put toward the new tranny...when the day comes.

Proper maintenance can be priceless in most situations. I would consider yourself lucky due to how long your trans has continued with possibly dirty fluid and the additives have probably been used up as well.

I would look at this as a sign of how durable the 65E'* really are.... I'm at nearly 166K and putting more power to it daily.

I'll have to look it up and see what'* recommended, if anything, but IIRC the normal interval for tranny flushes is normally considered to be 50,000-60,000.
