5spd Swap in 89 Sierra
Carsnguitars86 posted a topic in New Member IntroductionsHey guys. I bought an 89 GMC Sierra K1500 a couple of weeks ago. It has a 350 in it too. It has a turbo 350 trans in it now which I'm not a complete fan of. I had a 95 Sierra with a 5spd in it and absolutely loved it, Looking to make this truck I got a manual. Any idea on what a good 5spd trans to use? Will I need to make any modifications to the drive train...like a different transfer case or axles? Do I need to get a different PCM? Any information would help. Thanks, Bryan

I have a Silverado Sportside pickup from 1989 with a 4.3 Liter V6 engine. I have now removed the 4.3 L engine and fixed up the engine room with new paint and wiring and so on..... and i am about to put in a 5.7 L V8 from 1989 to get better perfomance. My Question is: On the torque convertor it is a label with: 8653702 on. Must i change convertor for the new engine (5.7 L), and if so are there anything else i must change ? If so what convertor number is for 5.7 L V8 engine (Gasolin) Best Regars from Finland Patrik
