After being on boost for a year and change my transmission is not shifting in reverse or 1st gear..(auto).. I pulled to code and its P0740.. The tranny never overheated or anything i have a cooler and tranny temp gauge.. Im thinking i just need to replace the shift solenoid assembly..Oh well

 

Wow I'm surprised it lasted a year. That tranny cooler sure does help, I can't wait to get mine. Ever think of doing the VB mod? It might help that tranny last a little longer.

 

When I do the shift solenoids im gonna put the trans-go HD2 kit

 

If you put it in park or neutral. And rev it real quick, do you feel the car jerk forward ?
Might not be a solenoid, if it was i dont think revese would be affected since that engages mechanically via shifter n not solenoid. Unless 5AT is different.

 

I feel car car jerk in park and neutral... I got da 4matic.. it does rev freely..if i give the car gas in reverse it even goes into boost but just rolls back..

 

Sounds like the tranny is hurt man. I wouldnt waste time/energy putting transgokit and new solenoids, to then find out it wasnt solenoids.

Thats EXACTLY how my previous tranny died. no reverse, jerks when you rev in park/neutral. Basically the clutches welded themselves together from heat.

 

It happened to me with my first maxima.... sorry, but your transmission is no more. I went to a transmission shop, they rebuilted it and I asked for a vb mod and I added a dr with a big oil cooler. A year later, I swaped a VQ35 and the transmission lasted for another year.... Then, I promissed to myself, no more automatic....

 

the man you're shaking hands with in your sig will be very disappointed to hear that

" if you ain't breakin' sumthin, you ain't racin' "

 

Your SO right! I beat the crap out of my cars

Even my 99 max, I blew the engine.... Damn cams spacers!
They dont like reving up to 8K! Going to be welded next time.
I'll start a built thread soon, so you guy's can follow our work and give some precious inputs!
My best buddy VQ'ed(who posted more often than me) and I, bought turbos together (R33 stockers)
and we are planing to go DET now.

I think he would understand, my previous auto kicked my ballz 1 time too many and too hard!
More to say, it's so pleasent to shift, rev match, clutch kick ....

BTW, Nealoc, Nismology, Jime, Grey, Streetz! I really like your work, and how much you share your knowledge!

So back to topic...
Will the OP going to rebuilt or swap????

 

Gettin another tranny..

 

Best of luck with the "new' one. As we said, VB mod is a MUST, the DR mod is so cheap that you would'nt do it and dont forget a oil cooler.(You might, also bypass the radiator oil cooler)
