If its a VG30 you could convert to a RE4R03A out of a 300ZX, big job and would probably need ZX ECU and matching TCU. You will need a big pair of hairy nuts and staying power.

Yeh they come with that gearbox or the cvt couldn’t I just plug that gearbox in and buy the ecu from another 4 speed gloria ? Looking for the easiest and cheapest way to get it back on the road 

[Rusty Nuts]

No unfortunately not, there is a seperate TCU (transmission control unit) required for the Jatco RE4R03A and the TCU HAS to match the ECU. A Gloria set would of course work.

Have you got issues with the CVT?

Would need TCU + gearbox at a minimum. Not sure about ECU's. If you're in Aus there have been some wrecked Y34's, Import Nation parted one out a while ago.

Yeh I bought it really cheap with no gearbox the cvt broke and has been taken out. I’m looking on eBay and I can buy a ecu and tcu for the 4 speed but is ther any chance that would link up to any/most 4 speed jatco box’s because they are used in quite a few Nissan’s

No, the TCU's are matched to car and ECU and box, been down this road. But hey you don't need to believe me, just keep asking the same question a different way and somebody will give you the answer you want to hear.

Yeh no worries thanx if I buy a 99 Nissan gloria tcu and ecu off eBay then buy a  Jatco RE4R03A it’s not going to work ? 

[Rusty Nuts]

As long as the ECU and TCU are for a RE4R03A  then you will need a speedo drive of the correct ratio to match your Diff the correct wiring loom and probably a dropping resister. Hopefully the Throttle position sensor for the CVT will be the same. If not one of those too.

alright no worries thanx for the info
