K so I have an 03 g35 sedan 5 speed auto the car is great I love it used to burn oil but I fixed it with a treatment of BG oil flush and moa and run 530 am soil engine is in excellent shape and no noises with 280xxx km. Used to burn oil every 1000km now doesn't burn a drop. Anyways getting on with the tranny. I was driving it lateltly and notice that when I'm driving rpm is rising and I need to step on the gas more for the tranny to shift into 3rd gear once it shifts in u feel a little jerk and than its fine. It does it with 5 too sometimes. I don't know if I need some solenoids or a rebuild or what but the tranny does sound like its dying and I want to repair it just want some opinions of what u guys may think it is u can hearthe engine getting loud and revvig sometimes to 5or6k just to shift into third. what donu guys thinkbo should do the fluid is fine just changed it after all this stated happening I want yo keep this car all stock cause I'm still running with the same engine and trannyalao I wouldn't mind having some more juice while I rebuild the tranny what kit and flywheel etc would u recommend for extra juice and stop thos problem lol. Also does anyone have a DIY for dropping the tranny on 5 speed auto. In might drop it take it to a tranny shop with the parts recommended and get them to rebuild it



thanks

 

Change the fluid first. Always start there. Fluid problems can lead to the torque converter failing to lock or engage propery, inadequate line pressure, and insufficient lubricity for the tranny itself. If that doesn't fix your 3rd and 5th problem, start digging deeper.

 

I already changed the fluid and its still doing the same problem. I could take a video of whats happening if that would help. Love the car but its driving me crazy

 

Did you use the Nissan J-matic fluid? Sometimes - though this is not necessarily ALWAYS true - using a different fluid can also cause problems. Some full synthetics, for example, have too thin a weight to stick properly, or are too 'slippery' in the torque convertor. Someone with more experience with the JATCO 5AT can chime in, but incorrect, insufficient, or dirty fluid can cause the problems you're describing.

 

When trans fluid changed did you notice if color was a bright red or dark/black ?

If color was not a bright red than its an indication of clutch wear, with miles on vehicle and driving habits it maybe normal.

Slippage is from improper line pressures, clutch wear or both.

You can have line pressures checked by a tranny repair shop.

Auto Trans does not use flywheel.

Internals can be upgraded using an ALTO Red Eagle Kit. Complete kit is geared for the Titan truck Trans but 6 out of the 7 clutch sets can be used (All but Reverse Clutch Discs). Kit will also add two extra clutch discs to the Input and Direct Drum Clutch sets. Cheaper alternative is to buy the Input and Direct Drum Disc Sets only. It took me 9 mos to locate a complete ALTO rebuild kit and cost $700.00

 

Maybe when I try driving triptonic don't do it anymore but the 3rd gear would vibrate and hesitate a bot and the fluid was nasty when o pulled it out I used one of those machines hooked it up to the two cooler lines and ran 16 litres of fluid through the tranny. But this was happening before I even touched the fluid. O know a lot of guys say don't use machines but my opinion are there great my car doesn't burn a drop of oil and I dont even use that Lucas stuff I just used the machine and am soil 5w30 and the engine is sweet and the original with 275xxxkm

 

Where did you end up finding the complete ALTO rebuild kit? I hear their products are top notch.

Awesome,

did you happen to put in a higher stall torque converter while putting in the Alto Clutches?

 

You recall the pricing?
