You need the truck up in the air and you have to completely drain the block. But, most of the time - it's not the heater that's bad, just the cord. I've had to buy several. They tend to burn out at the connector where they plug onto the heater-prongs.micvale1;1578704; said:that answered my ? thanks is it a big job changing the block heater it seems mine is'nt working on the 86 gmc
When you say "pair" I assume for the $350 you're also getting the transfercase and intermediate adapter?micvale1;1580878; said:thanks alot for the info on the block heater cord bought a new cord today and its working fine and i found a 700r4 tranny and transfer case today its out of a 85 jimmy 4x4 it was bolted up to a 305 but the guy said it was the same as my 86 surburban 4x4 he want $350.00 for the pair
The hard shifting ought to be easy to fix - sounds like a simple TV cable adjustment. A seal leak is a different story. I've never had a 700R4 actually go bad as far as running goes - but I've had several lock-up converter clutches go bad and MANY 700R4s leak oil out the front so bad - I had to pull and fix.micvale1;1580957; said:i have a 700r4 in the truck now but the clutch seal are going its has a hard 1st and second shift when cold its ok when warmed up,, the $350.00 1 the transfer case is still bolted to the tranny,,, tranny shop wants $1300.00 to rebuild the 1 in my truck
I do all my own auto-trans. now - it is MUCH cheaper and I like to know what's going in. A few years ago - I lost my 4WD function in my Subaru. Went to a shop - guy shook his head - and told me it was a common problem that would cost $1500 to fix. I came home, ordered a trans. kit and book from Matco. Ended up - after some education - I fixed the trans with two hours works and only used a small portion of the kit. Total job cost me $135. What ticked me off is - the shop had to know that my 4WD clutch pack was accessible without removing the transmission - but they failed to mention that.micvale1;1580995; said:how do u adjust the tv cable i'll try that,,, i'll even try rebuilding it myself i always thought it was a hard job .. they told me that the clutch seals inside the tranny were getting weak and it was just as much work fixing the seals as it would be to rebuild it,, it was just going to more money for the rebuild parts
Problem is - there is a LOT of know in regard to needed modifications, new parts, updates, etc. A person working on auto. transmissions every day - is usually aware of these things. Some of the mods. are considered - sort of - "trade secrets." Sometimes a double-thickness gasket added here, or an oil relief hole drilled there, can greatly add to reliability. So, to a good overall mechanic - who does NOT usually work on automatic transmissions - recent knowledge is the key to getting the "best bang for the buck."High Sierra 2500;1581649; said:By the way, there isn't that much inside one of these transmissions.
