hello i am new to this, but i am having issues with my 3.0 r150f transmission swap onto a 3.4. i have a 1996 tacoma with a 3.4 and i put a 94 r150f 3.0 5 speed in it.

I kept everything on my motor (whole clutch assembly) the same and put a 3.0 throw out bearing on the transmission. took me a long time to make the transmission fit but after getting it all bolted on and ready to go, i push my clutch in to try to go for a test drive and i can’t get into any gear! it’s almost like the clutch isn’t engaging all the way maybe? but i made sure the slave cylinder is pushing the fork and it is, but still not going into gear.

if it makes a difference i put the 3.4 slave cylinder on the 3.0 trans because the 3.0 slave cylinder wouldn’t fit since the header was in the way,but i wouldn’t think it would make a difference. if anyone could please help i would greatly appreciate it more than you know, i am very frustrated about this and can’t think of why it’s doing this, thankyou!!!

 

From what you’re describing, this really sounds like a clutch disengagement problem, even if the fork is moving. The key issue is that movement of the fork doesn’t always mean the clutch is actually releasing fully at the pressure plate.

A few things stand out in your swap:

First, mixing 3.4 clutch components with a 3.0 throwout bearing and different slave cylinder setup can easily create the wrong travel or preload. Even a few mm difference can leave the clutch partially engaged, which would explain why you can’t get into any gear.

Second, using the 3.4 slave on the 3.0 transmission might be causing a hydraulic travel mismatch, especially if the bore/stroke is jeux-casino-iledecasino.com different. That can look like “it’s pushing” but still not fully releasing the clutch.

Before anything else, I’d recheck:

• Proper throwout bearing match for the pressure plate
• Full clutch disengagement (not just fork movement)
• Bleed the system again thoroughly
• Measure slave travel if possible

In most swaps like this, the issue ends up being wrong combo of clutch + bearing + hydraulics, not the transmission itself.
