Hello!

I got a R33 automatic 1997.

I changed the gearbox 3 weeks ago after the old one wouldnt go to 3rd or 4th gear. The new used one got put in and i used Redline D4 transfluid. heres the problem..

When i put the gear in D i goes with no prob up to 2nd gear then it stops there and if i let go of the gaspedal from 3k rpm to 2k rpm the engine doesnt slow the car down it just falls to 1k rpm, but if i put the gear in 2nd it stays at 3k rpm and when i let go of the gaspedal it brakes the engine slowing it down. had this simtems on other gearbox to but i could go in 3rd i think and about 3.5k rpms it slipted but maintained speed. so im wondering could this be the A/T ecu or the Main ECU in the car or did i get a faulty Gearbox??. And if so any knowes were to get spare parts couse here in sweden we aint got them, and iv even called some ppl in Uk but they didnt have this A/T ecu only the Main ECU for A/T R33.

Well sry for the english. I aprichiate any awnesers and help

It certainly does sound TCU related.

Someone with an R33 will have to confirm for you that it's a separate TCU and not one with the ECU.

ECU = engine control unit

TCU = transmission control unit

Yea. I´v been trying to find some one in Sweden near me with a A/T R33 but its hard i think heres only about 5 A/T r33 rolling the streets, Well in first hand ill check the TCU and then The ECU couse the ECU has 3 outputs for the TCU so maybe its that.

Thx for the reply

      Why am I hitting a power wall with my stroked RB25?

      By TurboTapin · Posted

      I couldn't agree more. I should have started from the get-go with a NEO or solid bucket conversion. I started looking into converting over to solid lifters yesterday. Now for some reason I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  But I see no mention of this on any of the Tomei documentation. It just states I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!? There's no way it's that simple, I must me missing something?

      "Cheap" bolt on turbo on RB25DET NEO

      By Kapr · Posted

      @Murray_Calavera iam just considering options 🙂 of course it is very expensive so that why i ask here 🙂  @joshuaho96 I looked at that GCG hybrid(i remember looking at it few weeks before) So this is "that" hybrid where i send them my turbo and they upgrade the inside to Garrett stuff and then they send it back. It cost around 1200-1300 USD which is FAR cheaper than the HKS and it is what iam looking for(i just do not have experience like this...to send something off to "upgrade" ) @tylink720 that is like 150 USD turbo no? 😄 I dont think i have the "ease on my mind" with this kind of turbo. I just put over 7000k USD to "LINK" up my engine...dont want to blow it up with cheap turbo 😄     EDIT: https://www.cj-motor.com/gcg-turbo-charger-for-nissan-rb20det-rb25det-high?srsltid=AfmBOooVeOZ6CZ6r1AIv5m-KPaa6BvudIPJTY8LW78khkd-gQlsaCht9 I looked at this and it seems ok? It is that CGC hybrid and it costs around 1250 USD (with back shipping). Do any of you have experience with this hybrid on NEO turbo? I quickly look thru the forum/web and it seems very good.
