Can't Shift Into First

[Speed Buggy]

rcecale - how is it going? No new news for over a day, I am waiting with baited breath. Fingers crossed for the test drive.

[rcecale]

Waiting for this weekend to hang the engine/tranny. Trust me, as soon as there is any news to report, it will be here. Thanks for the interest, though!

What an amazing thread. I think I've put off more than ever attempting this though. I know you say it's been really easy but I'm sure I would mess something up. Knowing what & what not to replace along with forgetting how it all goes back together scares me. I can imagine having a number of pieces left over at the end

Great work though and at quite a pace too.

It's really not that hard. I have never done any major engine work before, and was always scared to even think about a transmission. If you follow the bently and advice here, it is very doable. The neatest part about this is that you get to see how a transmission operates. It facinated me to play with the syncronizers and see how they work. I still can't believe how small all this stuff is, and how much torque it puts up with. With all that being said, my tranny is still not back in the car yet, so I might change my tune if I get it back in and it doesn't work. I don't think that will happen though.

This thread is what convinced me to pull my tranny and rebuild it!

Edit: the price of all these parts (for their size) is far more scary than not knowing how to put the tranny back together for me.

Chris,

Honestly....seriously...if you think you need to have this work done on your tranny...do it! I felt the same way you did when this thread first started. But, with the encouragement and assistance I receiveved from EVERYBODY (including the rave reviews on my photos! ) it really has not been that difficult. Scary at times, he!! yes, but difficult, no way.
I was fortunate enough to have my digital camera which allowed me to post pics of my own parts and didn't have to worry about showing someone else's pic, which "kinda showed" my situation. Get one...it really made a difference.
Aslo, don't be afraid to ask questions. I know some people got a few laughs or chuckles at the fact that I didn't even know where my oil drain plug was located....so what? I know where it is now! And no, I was lucky enough not to have dropped the engine on top of myself as one person mentioned. I can't stress it enough...ask your questions!
Most importantly, though, like CD said...having the parts in your hands and actually playing with them, watching how they work, you really get an understanding of how things are supposed to be. And it really is/was pretty simple. Just take your time, and do it right. The guys here won't let you make mistakes, but you have to pay attention to what they're telling you. Like I've said before, if I can do this, anyone can.

If anyone was interested, it looks like this Saturday morning at 8:00 is when the engine/tranny is going back into the car.

Looks like the local Pelicans are going to come through once again! If all goes well, I should have pictures of the car, in motion, by the end of the weekend.....geeze, do you think I'm getting excited???

You go Randy! Dont be discouraged when the shifting is pretty tight for the first week or so. It will settle right in after a few hundred miles and you'll be lovin it! It will also probably take you a few days to get the coupler just right. I'm crossin my fingers for you!

How similar is this to a 901? I'm thinking that someday I may have to do the seals.

[rcecale]

H.G.P.
I'm certainly no expert, but during the course of this thread, I have looked quite a bit at the make-up of the 915 Transmission. Also looked at the 901 and while they certainly ARE different, the differences don't really seem all that great.
In Wayne's "101 Projects" book, he actually uses the 901 in his Project on "Rebuilding First and Second Gears" Might be a good idea to pick this book up and check it out.

Randy - I'll be on a soccer pitch all day tomorrow, either reffing or watching, but my mind will be on you and the reinstall. I have pretty much decided to DIY because of you and CDiercks, and the threads you have referenced and the help you have received on this site. Have fun tomorrow. Look forward to tomorrow night's post.
Cheers

Well, it's hung....sort of...

Jay and I got the engine mount bolts in and secure. The tranny mount bolts are a different story...I think.

Picked up a replacement tranny mount bolt yesterday to replace one that had some messed up threads. Now, it seems, that the bolt's shank is just a little too long, causing it to bottom out before it can be tightened all the way. (The weight of the tranny is hanging from the bolt, but the big washer is still movable. I can still spin it around the bolt.)

Another thing we weren't sure of was the mounts themselves. I took a couple of pics because it looks kinda odd. Is this gap supposed to be there? I know they are "flexible" joints, somewhat, but is this correct??

bump?

[Jim Sims]

Gap, loose washer and bottomed out screw are not correct. What was the part number and length of screw you obtained? I'm assuming you obtained one of the special pointed OEM screws. The correct part number is 930-375-317-00; it is a M12 x 65 mm long. There is a chance you ended up with a 911-375-317-01 which is for the the 87-89 G-50 transmissions; this screw would be 68 mm long and may be part of the problem. There is also supposed to be a spring washer (wave type) under the head of the screw- PN900-027-017-02. Take extreme care that you do not cross-thread these transmission support to body screw threads and coat them with anti-seize compound to ensure they will disassemble in the future. You're almost there! Cheers, Jim

[rcecale]

Jim, according to my invoice, the bolt I got IS part no. 930-375-317-00...the correct one. Also, when I compared it to the old one, it was the same length, with the pointed tip.
The odd thing about this is that both mounts have that same gap. I tried the good original screw in each side, and I tried the new screw in each side, but the gap remains, and the left side screw always bottoms out.
There was no spring washer on either side when I removed them. I can pick up a pair of spring washers, but do you think the mounts themselves may be bad?

Randy

[Jim Sims]

The spring washers won't make much difference as they're not very thick. Did you remove the mounts from the front transmission support and reassemble? Is there a shim plate installed between the transmission and the front tranmission support? Jim

[rcecale]

I did remove the entire support assembly, when I had the tranny apart, but only to clean it up. There was no shim installed between the tranny and the support assembly. I didn't remove either of the mounts from the support.
Also, the bolt pattern for the bolts thet mount the support to the tranny preclude improper installation...except for maybe upside down, and that's not the case here.

Randy

[Jim Sims]

Looking more closely at your images appears to indicate your mounts are on top of the of the front tranmsission support. They should attach from underneath and pass up though the holes. Which way are they? It's hard to tell from the images. Putting them on top effectively reduces the thickness of parts in the grip of the screws making the screws too long? Jim

[rcecale]

Jim,

I guess what you're telling me is that these mounts have been installed incorrectly? If that's that case, they been installed incorrectly for longer than I have owned the car.

I suppose that's possible, just kinda wild to think they've been for so long. I have to say, I'd much prefer to have to reassemble them correctly, than to have to shell out the cash for a new pair of mounts.

I'll throw a jack under the tranny tomorrw after work and pull the support assembly and have a look. Here's a catalog pic of how it's supposed to be assembled.



Randy

[rcecale]

Took a couple of shots of my installation. Both sides are installed the same way.
