New Transmission Section on Main Site

[bszopi]

It was brought up in a different thread somewhere on here about possibly adding tranny info to the main site. One of the points made was so that I wouldn't have to continue to post 4Txx-x info anymore. Hey, that makes sense to me!

I would like to see the section grow to include all trannies that these engines have ever been bolted up to. With that said, any info that people have to provide would be great. I have just about all the info available for the 4T60-Es, but that's about it. Please email me if you have info about other trannies and I will get it up on the site.

For now, here is the link to what I have up for the 4T60-E right now:

Feel free to add this for the different gear ratios:

You know, I'm usually the one that posts that (cause I was the one who orignally did). I wonder why I didn't come across it in my online files?!?! Oh well, thanks for bringing it up and I'll get it up right away.

Ok, well... it took FOREVER (well... I got it down after the first 15 or so), but all 4T60E TSBs are now on the site, and in a "printer friendly" layout. Hopefully some of you can/will use them so that not all my hard work was for nothing.

On a side note, we are planning on getting as many TSBs up for all of the trannies and engines. Its gonna take awhile, so don't expect anything soon, but look forward to it in the future.

I thought I saw somewhere recently that someone had done a writeup on the filter change, wish I still had the link......

I race in a front wheel drive class on a 1/4 mile high banked track. We need lots of speed and RPM's coming out of the turns. I cant get 2nd gear to kick in and believe my tranny is bad. I have a sunbird with a 3.1 and wondered if there is a certain tranny that could bolt up that would be better for my car than the one that is on there. I have heard from most people that they are all the same, but I think otherwise. I have also heard that the trannies out of 3100 are better and that you can snip a wire and make a artificial shift kit. Basically, what is the best tranny that will bolt up and is the shift kit thing true???

i think the link is bad...brings me to the main page

also you can 4.40 fdr by using the 28/37 drive/driven gear ratio, but you need a shorter custom chain

here are some

[prophiseer]

I've got an ass-load of info on the T40/45's

[bszopi]

Wow... link from the past. What do you have? Zip it up and send it over and I'll try to get it on the site.

[prophiseer]

I'll try and scan some stuff out, it's all GM's bunk outta a 4T40-E GM tech manual. Basic operation, sensor descriptions and electronic range's, etc. tranny power flow, mechanica op. Flow charts if you REALLY want them (color too, hell-o-lot easier to read than B&W).

[bszopi]

I have the same manuals for the 4T60E and I have only put a limited amount of that info on the site. Most of it is too much for the site. If someone is going to go that in depth with a tranny teardown/rebuild, they really should have the actual manual in front of them.

[prophiseer]

True, very true . . .

well, I'll scan out some of the basic stuff; power flow through the tranny & operation, basic part assembly diagrams, etc.

[LeftVentricle]

I'd like to request information about the ME9 440-T4. I haven't been able to find anything about it, aside from the gear ratios posted on the previous page. What kind of power can it stand? Can the guts from a 65HD be installed, since they share gear ratios?

Much later edit: nm, I'll just start a thread.

[bszopi]

Are you talking about the 440-T4 (4T60), predicesor to the 4T60E? If so, then there really isn't anything that will interchange. There are significant differences between the 4T60 and 4T60E, let alone the differences between the 4T60E and 4T65E.
