| 1447394 | 2018-03-27 19:06:00 | I've not gone and converted ME to sillimeters, but to be understood, I did a miles-to-sillimeters conversion just for the sake of this conversation . I won't do this again - so mark it as a milepost . OK - I have a 2000 Chevy AstroVan with a 4speed overdrive automatic transmission in it - it's a 4L60E - electronically controlled . It has 367,968 . 459 Sillymeters on it . It has been somewhat regularly serviced wherein I have actually changed the fluid in the pan and the filter four times so far . The singular problem I had with it was a busted 2/4 accumulator spring that was accessable from outside the transmission, and it is right back to good shifts, great mileage, fuel-wise, and reliable as all day . My 1989 Chevy Blazer has had a couple of transmissions in it - not built by me - but the first one was trashed by the installer when the alignment pins were missing from a junkyard engine and the transmission ate itself to death . I currently have a 7-speed automatic in it with over 200,000 miles or 321868 . 8 Sillimeters on it . It's not an Allison, but I converted the THM440T4, that I added another planetary set and clutch pack in it to get all those gear ratios for heavy trailer-pulling . My Isuzu has 485,000 miles -----> OK - it's got: 780531 . 84 Sillimeters on it . The manual transmission 5-speed in it is just now making a tiny bit of gear noise in Reverse - that's all . There is no Golden Rule by which I can honestly state that any transmission is 'bad' - haunted, maybe . . . . but not really bad . There are bad designs - but they too can be made to work as best as they can - even if their design is hampered by poor quality metal alloys - which seems to be the biggest bugaboo these days . I dislike Euroboxes for their overall cheapness of alloys - it seems their metals are forged by unwed mothers in thatched cottage back yards on a peat fire and cast in the dirt from a ladle . Surprisingly - I like Indian and Pakistani steel very much . They have terrific control of their alloying processes and their steel is vastly superior to even German alloys . Japan is/has fallen from my graces as a great steel producer by now too . Their day is gone - their forges and smelting pots are aged and decrepit by now and need replacement - but alas! The US Lend/Lease Pact is long dead so the money and gear has dried up . Back to transmissions - 'clunks' are never a good thing - some can be ignored for a time - and some are yelling at you as loudly as they can that they need attention - NOW! One clunk that I didn't see noted here - it might be, but I just cruised through this post - is that the CV joints/shafts might be worn out too . Motor mounts are close second clunk-maker - since there should never clunk from the transmission itself . Those parts just slip and slid, burn up --- or fracture, causing loss of one or more driving ranges -- eg: only having PARK - REVERSE and many NEUTRALS . |

| 1447395 | 2018-03-27 20:05:00 | I don't claim any great mechanical knowledge, I managed to do a few repairs here and there before engines started getting complicated and that's about it. I have noticed that those big old american vehicles do seem to be very reliable, if not particularly well suited for narrow winding NZ roads or very good at going around corners (generalisation, I know.) One story I remember is a friend of mine who drove a Holden statesman, (an Aussie car very much based on american GM designs en.wikipedia.org(automobile)). It had 400,000 + miles on it which was impressive at the time. It turns out the first 200,000 miles went through two holden 308 engines and the remaining 200,000 and counting was on a single Chevy 350. |

| 1447396 | 2018-03-27 21:54:00 | Hey Joe.... millimeters et al metrics work good. USA is part of only three great powers who don't use metrics, the other two being Myanmar and Liberia. It seems that these 3 countries will have to be dragged kicking and screaming into the 21st century. Ken :) Ps What calibre is your new Glock? |

| 1447397 | 2018-03-27 23:30:00 | I got a 10mm Glock . Feels very nice and controllable to shoot . Massive firepower with a good long range capability and huge impact at 1350fps w/200gr bullets . |

| 1447398 | 2018-03-27 23:35:00 | So, that's 0.393700787 inches? Ken :) |
kenj (9738) | ||
| 1447399 | 2018-03-28 03:30:00 | Yeah - we call it a 40 caliber. It's so close to .40" - and calibers are rated in inches - so it fits. BTW: the 10mm and the 40 caliber share the same barrels - and I'm told the Glock 10mm can safely chamber a 40 cal - but I wonder at the shoulder height of the 40cal v the 10mm. The 10mm case is a lot taller and I don't think the 40 can fully sit in the receiver and stand proud enough for the firing tray to reach it to set off the primer. |

| 1447400 | 2018-03-28 03:33:00 | Sorry being so late to answer - we just got our electrical power back up and operating. It was down for a few hours tonight. I imagine a car v power pole out on Shoshone Loop, somewhere. |
