well it finally happened, and the irony is i was on this morning saying how much better it was. but u fix one thing and another goes. my transmission downshifted out of nowhere and banged so hard that i think my transfer case hit the underside by my seat, well i have only first gear and a possible second and have no reverse at all. my question is if any one on long island know a reputable trans guy and how much i might be lookin at. im thinking a rebuilt tranny and transfer case and a new torque convertor, possibly around 2,000. i had an 84 blazer 2.5 (iron duke) 4x4 700R4 trany rebuilt and thats what it cost. if i could get fast replies that would be cool cause aamco is coming tomorrow morning for it. i'm hoping for external problems only, but thats not my luck!

 

If you can do it, get yourself a reman unit. Those trans shops often screw things up. I'd just purchase a reman unit from a reputable online supplier (MonsterTrans.com or JasperEngines.com come to mind). Then if you can not do the install yourself, just pay a mechanic to install it.

If you wanted to do it more on the cheap, you could put in a junk yard tranny, but if you are expecting to pay $2000, you could easily get a MonsterTrans or equivalent and have a mechanic install it.

*EDIT* - is your truck a 4wd or 2wd? Also, does anyone know if his is a 700R4 or a 4L60 (non-E)?

 

hey kyle, i think i got a 700R4 4x4, yet ive never swapped trannys before nor do i think i have the capabilities. i'm working with jack stands and several jacks, pnuematic tools, and enough other tools to open a store, but can i do that in my situation and do i need anything in particular. plus one thought came to mind, when i changed my oil press switch i had to remove the tv cable and bracket. well i dont know if its self adjuster was working, cause i had to fine tune it when it was shifting to early and then to late and back and forth until i found the right spot. thanx

 

Being a '92 and a 700r4, it shouldn't be difficult at all. It can be done with jack stands and hand tools given the proper motivation. It won't be the easiest thing, but it would sure save you money!

Basically, remove the front and rear drive shafts. Then remove the transfer case. Remove any linkages, cables, etc. Then unbolt the dust cover & TC. Support the transmission on a jack and remove the transmission cross member. Lower the back of the transmission down to make it easier to access the top bell housing bolts. Remove the bell housing bolts and separate the transmission from the engine. You may need to support the back of the engine as well to keep from damaging your fan shroud. But that is basically it.

Now I know it's a bunch easier, but I swapped the transmission on my Chevelle in under 45 minutes one afternoon by myself. Air/hand tools, jacks & jack stands were all that were used. But the TH350 is lighter than a 700R4 (IIRC) and I was able to pick it up under the car enough to get a jack underneath it and hoist it into position.

 

My parents are gonna hate you kyle, but im willing to try it. why my parents, cause i have to set up shop in their back yard. you make it sound a lot easier then it probably is cause i know my blazer and nothing ever wants to come off of it. but i was on ebay and a local guy has a rebuilt, looks real clean for 750. so im gonna try it, but after i get the estimate and make sure its nothing external. it'll cost me for the tow and i think the diagnostic test is only 40.00, but add 750 and its still cheaper then 2,000. if you know any one who might have one in the ny/long island area that would be cool. hoping for sucess
