I have been swapping my tranny twice now and the same problem is happening. When I am driving in 5th gear, the shifter would automatically “pop” out of gear and go into neutral. This has really been a puzzle to me. I cant seem to find out the true underlying cause. My car was originally an AT and converted to manual. Both trannies were JDM B16a S1. I had my motor mounts, shift linkages examined for misalignment or wear and still could not come to a conclusion. They told me that Im either unfortunate that both trannies were coincidentally bad.
The car drives well 1st- 4th gears in both trannies no problem except always 5th gear. I had read some forum members mentioning that they had a b16a with an LS 5th gear setup.
MY car has regular b18a with i/h/e . Is there such thing as incompatibility or do I need to modify the B16a tranny’s 5th gear?
Lastly, my friend’s G2 also had a AT-MT swap and never had this problem. Only difference is he had a LS tranny.
i was cruzing down the freeway and my tranny poped out of gear than my tranny took a ****, the person that looked at my car said that my throuout (bad spelling) bearing was bad . try sitting in your car , and with the palm of your hand try hitting the shifter down, and listen for noise
I had this same problem after i swapped out my whole b18a to a b16a si a jdm tranny i knew what the problem was from the beginning so i got it fixed. I went to jiffy lube and got my tranny fluid changed…go ahead and do that…it should fix the problem guys…ONE!!!
