RE4R01A Disassembly 

Dunno if anyone else can relate but when you’re troubleshooting a gearbox these videos are gold.

The interior stackup almost makes me think the 4L60 design engineer went to work for Jatco and tooks his notes with him.

2003 INFINITY QX4 4X4 start car it will moved but after a min when the trans fluid warms it will no longer move in any gear. What could this be ? Worn pump ? Funny thing is when i turn the car off for 30 seconds or so it can move again in any gear, then will not longer move after 1 min or so. Every time. BTW great video a real master at work.

I have a 2001 Frontier, and the trans just started some weird stuff. My son has been driving it, started not gong into reverse, he added fluid, then it started stalling instantly when put in gear, checked fluid, was over filled, removed to proper level. Next day, same issue no reverse and he drove it 30 miles. I went to look at it and it has very loud grinding noises in all gears and has no movement in any gear, just grinding noises get louder. I can not roll the truck backwards, only forwards. Do you feel this can be rebuilt or possibly damaged beyond rebuilding? Thanks for the awesome channel.

hi good day i have a terrano 1998 automatic was drive good then its not sellecting any forward gear only reverse what can be causing this please need some help thanks

please help! Is it possible to have a leak get worse after a fluid and filter change? I'm helping my elderly neighbor with his frontier. Fluid smelled burnt, so he wanted new fluid and filter. I found shavings on the magnet and sludge, as well as brown fluid, I get it all put back together, started it up, and it had a leak from the top of the transmission where it connects to the bellhousing. It already had a small drip before I got to it. It's also been very neglected before he got it. Is it possible I dislodged some gunk that was keeping it a small drip?

thanks for the video very helpful,i have a 1998 nissan frontier pickup truck,some time when i put it in drive the truck don't move but it move in 1 and 2 ,what cause that.

Goodnight sir. I have a 2000 frontier 2.4. The reverse works only when the engine is warm about 5 minutes. Im guessing the seals are bad. Can u give and idea ? Thanks very much.

I am rebuilding one of these from a 2004 Nissan Xterra that had no reverse, i bought a new reverse drum, new pump, and new torque converter and a new complete rebuild kit with new steels and clutches all seals ect from Transpac , the accumulator seals the kit came with were D rings and the kit came with O rings too well if i put the D rings on those plastic acumulators will not go back in amd if i use the o rings the accumulators seem tight. i got a few duplicate parts in this kit or parts for another version of this transmission, mabey they are supposed to be this way?

Hello sir, would you need to remove the valve body to replace the output shaft?

I have a 98 frontier. All gears work including 4th under 40 mph. Anything more and it jumps back into 3rd. It also shifts back into 4th if you let off the throttle. There is no slipping. In your opinion does that sound like the end plugs, thanks in advance.

Do yall sell rebuilt transmissions? 2000 Nissan frontier 4cyl auto?

Rebuilding one of these and the planet carrier has roll pins in it to prevent the pins from coming out. They're also all very slightly loose in the holes so the planets have a tiny amount of wiggle caused by the shaft moving slightly in the carrier hole. There is also up and down play but the planets seem to be riding perfectly on their pins. OK to reuse, or should I get a new one?

Awesome video.! At least I tear down the tranny and found the damage inside it.. I can get the parts or get a good one.. Thanks Much.! jv

Can u swap the shaft out of a 2 wheel drive an make it 4 wheel? Is the vb set up to shift the same?

Tom how are you sir? Would the valve end plug issue cause the slow 2-3 engagement and late drive engagement? Thanks. Mike.

Hello sir I'm glad I found your channel. My wife's 2004 Nissan Xterra with the RE4R01A automatic transmission makes a light grinding noise right before it shifts to a higher gear after warm up. At 60,000 miles I dropped the pan and changed filter and added same amount of fluid I removed. At 100,000 miles I just did a drain and fill . Then at 120,000 I did another drain and fill because the car had been sitting for a year waiting on me to finish rebuilding the engine . Now the engine runs like new except for this transmission issue. Could it be the torque converter. I did forget to grease the area where the torque converter meets the crankshaft. Or could it me the Valvoline maxlife I've been using since the 60,000 mile fluid change. Should I use a friction modifier or go back with OEM Nissan matic d fluid. Any tips would be appreciated.

Is there a difference with the RL4R01A and RE4r01a torque converters?
