Isuzu 5 speed no reverse (Page 1/2) NuttyToe NOV 02, 06:55 PM New to Fiero's but have been working on cars for years. Looked through searches and couldn't find anything helpful. Just swapped in a junkyard 5-speed Isuzu in to replace a blown up 4-speed. Everything has been fixed and shifts great 1-5 WITH AND WITHOUT CABLES. However, I cannot get the car to shift into reverse no matter what I do. Cables have been adjusted numerous times to try and help and tested with them disconnected. It just won't go into reverse. Ran 1-5 on jack stands and no weird noises or anything. I'm thinking the trans reverse gear is bad or something, any suggestions? Patrick NOV 02, 11:28 PM I assume you installed a 5-spd shifter? If you disconnect the cables at the transmission, are you then able to move the levers on the tranny and put it into Reverse?

It is a 4 speed shifter but modified it so it is the same as a 5 speed regardless. With the cables completely disconnected I cannot get it into reverse. Goes into 5th fine but can't go into reverse. skywurz NOV 03, 01:43 AM Did you flip the selector over if its not from a Fiero? Probably dumb question but you are not going 5th to reverse are you? It will lock out. Patrick NOV 03, 01:45 AM quote Originally posted by NuttyToe: With the cables completely disconnected I cannot get it into reverse. Goes into 5th fine but can't go into reverse. Well, that does not sound good. I'm aware that Isuzu's 2nd gear can pack it in, but I'm not familiar with any Reverse issues. Perhaps a transmission expert can chime in here. fierofool NOV 03, 08:17 AM Since you're new to Fieros, I'll throw this out. The 4-speed has reverse located to the left and forward, up beside First Gear. The Isuzu has reverse located to the far right and back, down beside Fourth Gear.

I am not specifically going reverse from 5th, just know they are on the same shift fork which is why I included that. I've heard some people have broken shift forks and then they can't get into 5th or reverse when that one is broken. But my 5th works fine.

But yes not sounding too good, I'm thinking it's reverse gear gone out but not 100% since I feel like it should at least grind or something. It's almost like I can't get past the reverse lockout.

I was originally going to say "goes away", as 2nd gear just isn't there anymore when it fails, but I thought maybe that phrase might've confused you!
