i have a gsr from japan with an automatic transmission. i want to take out the tranny and connect it to an ls integra. would i have any problems? thank you all.

 

i might be stupid but i thought all gsr's had manual trans.

 

All usdm ones do but some jdm gsrs come automatic

 

yea, this motor is a jdm one that even came with an ecu for the auto tranny gsr.

It is splitting hairs because a GSR was never sold in Japan. The equivalent was the SiR.

OP, are you keeping the same OBD? Is there any advantage for the SiR automatic over the LS? I have never seen any gear ratios of the final drive for this transmission. I could see the shift points not being correct for the transmission if the ratios are too different. That does have potential for an automatic LS-VTEC since you have an automatic P72 ECU.

 

the jdm auto sir tranny is the same as the one out of the usdm ls.

 

forget auto, switch to manual tranny, auto sucks, MT ftw

i will keep the same obd. and the advantage to the SiR tranny is that it is a tranny that works as opposed to my gf's beat up ls tranny.

i bought this jdm gsr so that i could swap out the tranny for my gf, and take the motor to build it for my integ... killing two birds with one stone.

i have a manual b16 tranny lying around, for those who commented on manual over auto

but i need to know for sure if the SiR and the LS tranny are identical (or at least compatible with the LS motor). how would i go about finding out? check gear ratios perhaps?
