    700r4 servo pin

    It's ok snowflake, just let it go and learn transmission stuff. Hashtag peace.

    700r4 servo pin

    All right, no worries. Just wasn't sure what you were exactly looking for. So the short answer is: no the Corvette servo (or any other) won't affect the pin depth / band clearance. The longer version is: it changes the apply/holding force on the band with it's larger apply area. It also...

    700r4 servo pin

    All right... some confusing information here. First you say you want to put a Corvette band (?, there is a common upgrade to a Corvette servo not band). Then you say you changed everything except for the servo, what would mean you put a new band during rebuild as well? Ok, back on track...

    Air + fuel + spark = nothing

    Thanks for the replies so far. Timing chain crossed my mind. Don't think it's broken as it had compression, although not measured at the moment to be honest. Thing is, I saw the engine start and turn flawlessly then, 5 minutes later, not willing to fire up without a sound or a warning. It...

    TH400 kickdown solenoid connector leak

    You mean the inside of the prong connector on the outside of the case? Haven't had it, but probably possible if plastic has hardened out through heat circles through the years creating space to metal prongs.

    Air + fuel + spark = nothing

    There was less than 5 mins between a clean start and no starts. We put a start aid to prevent batt drainage during later attempts. Will check starter drainage to be sure.

    Air + fuel + spark = nothing

    Visited a befriend shop owner on my way to home yesterday. He's a very competent mechanic who builds high end cars with a lot of attention to details. What happened: he rewired and renewed the wire chaos, started the engine and checked if the new dynamo was charging, what did, then killed the...

    Changing differential, gear pattern issue

    You want both sides to be centered between crown and root as much as possible. Sometimes the gears are cut in such a way that you just don't get the school book results, no matter how much you try. All you can do is obtain the best achievable result and give it a spin.

    TH350 Rebuild

    Something's rubbing.... metal clad getting scrubbed or maybe some clutch material (HEG or Kevlar?) coming off?

    Changing differential, gear pattern issue

    Coast still looks shallow, but drive looks (very close to) spot on. Changing/chasing 1 thousand is very frustrating, because measurement errors/inconsistencies can make you run around in circles... I would finish it and tighten it up.

    Changing differential, gear pattern issue

    I would say again, it looks like you're close. Judging your last pics, it looks like you're a tad deep on the drive and a bit shallow on coast. Pull some like I said previously to 39-40 (edited my message when I saw I had mistyped 39-49, my bad). This should center your pattern. Never have...

    Changing differential, gear pattern issue

    Just to give you an idea what I'm talking about: first two pictures I took from a different place asking for advice. You see the difference in pattern quality/readability? I think you don't apply enough pressure or create enough resistance on the pinion for a good readable pattern.

    Changing differential, gear pattern issue

    Went through your latest pictures multiple times, wondering why your markings are so hard to read even with new gears.... What I think I can see is that @ 37 you're a bit shallow and overshoot @ 42. Best pattern should be then somewhere around 39-40. Make some good pics of the ghost pattern...

    Changing differential, gear pattern issue

    This one is giving us a headache.... but this is what I can tell you: - 28 looks better to me, not because of the actual pattern, cause I can hardly see a difference, but by judging the ghost pattern just behind the marked teeth. - I would give it a try because new gears won't work in one...

    Fluid leaking from the speedometer cable connection

    For sure it is... it's a 'normal' consequence of wear, abuse, misuse, neglect or a combination of all these factors 😉

    Fluid leaking from the speedometer cable connection

    You can replace the seal only, assuming there is nothing wrong with the housing (what would be quite rare).

    Fluid leaking from the speedometer cable connection

    Don't forget the seal on the inside of the bullet. It can leak from between the housing and driven gear as well.

    So, what is the least expensive way to install a 200 r4 in an 81?

    Take the 350 cross member, cut off transmission mounting tab, reweld to the back and you have a 400 cross member! And since a th200-4r has the same mounting distance as a 400...... you do your math ...

    Well, I bought a couple 200-4R's yesterday.

    Only produced for 10 years, but they made some changes to decoding. This work quite well for most years. Looks like yours are from 89 and 83.

    Well, I bought a couple 200-4R's yesterday.

    Yes, a shift kit (which is a registered name IIRC). A shift reprogramming kit will have even more upgrades. Transgo makes good quality kits for all amateur builders and even most shops. Only a few pros make their own kits or mix kits from their favorite vendor with own upgrades. 200's need...
