I used Peak, MaxLife, and Transmax ATF in my Sentra and it shifted like [censored]. Upshifts flared and/or slow shifting. Left the MaxLife in it because I was getting sick of changing it and 20k miles later it started shifting normal again. The trans doesn't seem to like ATF that's to slippery...

I don't profess to know what all manufacturers do when it comes to oil, but I did work at Nissan for 21 years and have some knowledge regarding that company's oil history. Back when Nissan Motor Corp (USA Nissan distributor) started selling oil under their own brand, the Japanese insisted on a...

Almost positive Nissan uses regular conventional oil for the factory fill. Nothing special. Change it per the service manual schedule and you should be fine. The 3.5 is prone to sludging so keep on top of the changes.

What's the issue with this oil and wet clutches? Too much moly?

Metric Vintage 1980 Suzuki GS1000S Actual, I have two of these. One restored and one in process.

Went though the engine on my '80 Suzuki GS1000, installed new rings, lapped the valves, new seals, etc, and was wondering what the general consensus is in terms of how long to run the initial oil fill before changing? Have Motorcraft 15w40 diesel oil in the engine now with about 150 miles on it...

I used to own both an '84 VF500 and an '87 VFR700. I loved both of those bikes for different reasons. The 500 had a noisy valve train which I suspect was a symptom of the problem although I never experienced any actual running problems. The second generation V4 engines, like the VFR, fixed the...

I don't understand what you would change oil wise due to these factors: High RPM, plain bearing crank, placement of camshafts, dry/wet sump. Please explain.

Redline is good, except when it's bad.

Adjusting valves is easy. I don't understand all the worry. One tip: before you remove the cams use some sort of scribe/paint mark on the cam chain and sprockets to assist in getting the engine timed properly again. Just double check your cam timing per the manual and everything will be fine.

Originally Posted By: SteveSRT8 Transmissions are about more than just line pressure. More is not necessarily the best thing. And most trans have a regulator to maintain the pressure regardless of RPM. If it's flaring, it's probably near toast anyway. Dex VI is the future. I bet if your trans...

Been away for a couple of days and come back to find all kinds of new posts in this thread. Thanks to all that have contributed. The shift flare is not "too" bad, but it's there. I can live with it but don't like it. Started to do some research about viscosity for the various fluids, I'm...

Originally Posted By: MolaKule Your fluid change may have dislodged some old deposits. Change fluid and try some Castrol High Mileage ATF and or add some ARX. The car has 26k on it. There isn't [censored] that got dislodged. The transmission just plain doesn't like that Castrol Import ATF...

Battery disconnect did nothing. I doubt this model has any adaptive learning that effects line pressure to lock up the clutches. I'm now wondering if a little shift flare (slippage) when upshifting is a durability concern? I'm thinking not so most likely I'll just run this AT fill for a year...

Okay, thanks for the tip. I'll do a battery disconnect before driving to work this morning. Fingers crossed... Regarding mixing the oil, that wasn't my plan but was surprised when four quarts came out with a simple remove the drain plug type fluid switch. Pulling the pan to change the filter...
