That engine will be in my 83 Fbody 2019 can’t wait

[@KonigWolfx]

Any word on a standalone tcm for the 8L90 in the works? I'd love to ditch my 6L80 in my Camaro!

[@SpeartechLSX]

We aren't developing a standalone 8L90 controller, but you may look into TCI or PCS. That's more in line with what they do.

[@AdMiRaLeDpIeTt]

I need this gargantuan engine to my Daihatsu Rocky!

[@dragus213]

what sort of shifter is needed for this thing? standard 4 speed auto or something else? also any support for paddle shifting?

[@mikesanto69]

FUCKING AWESOME CAN THE 8L90 TRANS GO BEHIND A GEN 4 lsx/ls2 OR ls3?

[@aguerra5344]

Also could a 4L60E lock up behind this transmission An work or no cause 2 totally different Gens?

[@ls1camaro92]

What gas pedal do you use for this harness?

[@bryson4777]

What tail shaft is that your using on the transmission? I have a 2019 Lt1 and need to change mine so it can fit in a g body

[@SpeartechLSX]

This is a truck 2WD transmission. You'll likely need an adapter from Sonax to convert to a u joint or modify the transmission.

[@garrychernoff6360]

HI, my car is lexus is-f, is the 8L90 can swap my transmission TL-80SN?

[@kassiusklay9806]

was this a wet sump or dry sump version of the lt4

[@3rdGenGuy]

wait, you can swap these 8 speeds in older cars?

[@SpeartechLSX]

Yes we have an LT4/8L90 in our 1969 Chevy C10 shop truck and it's running very good. We sell many harness packages and complete engine packages for older swap cars quite frequently too. We have a quick video of our 69 C10 with the LT4/8L90 here: th-cam.com/video/QZvNpJI_0nw/w-d-xo.html

[@MotorsportsX]

@@SpeartechLSX can you put the 8l90 behind a gen 4 engine?

[@slowmanEF]

Won't work, 8L90 requires the Gen 5 engine/trans computers for proper operation.

[@Dewreck]

MotorsportsX if you read the overview on the jegs website it says it will work with an adaptor plate

[@Tigersmundo]
