Ok i got the truck back from the drivetrain shop today. I didn't have time to mess with it and i need my second truck so the GF can drive one cause her tranny went byebye in the mazda.
Anyway i had them replace my cracked flexplate, instal a new 3200yank converter and instal some 3.73gears.

Anyway i didn't notice until after they were closed and i was a decent ways away that my gear selector does not go into park. I put it in park and it rolls like neutral except it won't start and like i said...no park.???

How hard is it to fix this cause the shop isn't open on weekends and i'd like to have the truck driveable.

Second i have been having some issues with noise from my leafs but now i noticed today at low speeds like say 10ish while letting it idle cruise...i can sometimes hear a ringing type of noise. Not the normal crazy sounds from the leafs....plus they normally make noise form loading them then they won't stop until i let off the gas even if i am at a steady speed.
Would you guess the ringing type noise is a problem with the truck or just the leafs making more strange noises?
I can't feel anything bind but i'm worried anyway.

Thrid how many teeth are on a 3.73 gear set? My 3.42 gears look just like the 3.73's did?????

How long should it take to throw a code as well? From a 3.42 gear to bumpped up 3.73 swap?
They did the 3.73 swap but i drove it about 20miles home and never got a code......plus the speedo/rpms seems about the same as they did before?

I need some ideas/help so what you guys got?

Finally i gave it some gas a few times...by gas i mean 1/4 pedal up to maybe 1/2 at best.
Around 4k rpms it breaks the 20's loose till it shifts at about 5200rpms...shifts rolls a mean second then is gone. This is all at 1/2 pedal or less.
Traction will be a problem nowadays....

 

I've been having this exact same issue. Mine wasn't the park neutral safety switch(yours may be). My transmission linkeage was a bit short so you have to extend it a tiny bit so it goes into park. I have to kind of lightly "jam" it into park to get it to engage.

 

park neutral safety switch....is that with the cable connections and all? I have not gotten under it to see whats wrong yet. Didn't feel like having the exhaust burn me.

I tried throwing into park kinda fast/hard. Didn't help any. I do know when i stopped for air and the truck woudn't start i was a bit baffled for a few mins haha.
