GMC Safari slipping problems

Filed Feb 10, 2005 · Transmission · 93,000 miles · CO

1998 gmc safari van automatic transmission model 700, failured at 93,000 miles due to a 3rd gear slippage. I found in my research to fix this problem this was common for gmc trucks with this transmission for this to fail between 90,000 and 100,000 even with scheduled service. Gmc agreed to replace with a factory rebuild, which they did but at my cost of $2,300.00, with a 36 month/50,000 mile warranty. I could not find any tech service bulletins or recalls on your web site, do you have anyother information. Gmc and its dealership is already aware of my product displeasure when I expect quailty and durability it was not there. Please respond, thank you.

Abs system failed. Dealer stated that it was not a safety issue, they still had brakes. *ak ABS failed when consumer pressed on the brakes to avoid collision with another vehicle. Abs light came on and stayed on. The loss of ABS was caused by the failure of internal brake module. Consumer declined replacement because when he was quoted by the dealer of the expense for repair, cost was $1300, and was told that vehicle will still have the same braking capability even without ABS. In addition, recall on dipstick, to indicate transmission resevoir. If dipstick is shorter, it would cause transmission to slip.

I have had more transmission problems from my 1991 gmc safari mini van than all other previous vehicles I've ever owned. I'm looking at my third transmission overhaul soon (seems like one every two years) and I don't drive fast and don't have a hitch to "pull" anything. Currently, my transmission slips into neutral when the transmission shifts from 2nd to drive. It went from happening once a month to approximately 4-6 times a day. The transmissions shops I've seen say I need an overhaul again. I hate this gmc automatic transmission.

97 safari consistently sets p1870 code, transmission slips when warmed up. The vehicle shift extremely hard (actually slip)1st-2nd-3rd. Hard enough a significant chance of u-joint breakage, uncontrolled tire spinning on ice/slick roads, (I have experienced),whiplash type experience under moderate acceleration. This sudden shift also attributed to causing interior components such as center console to shake loose. Several instances have caused items in center column cup holder to fall out and spill. Gm has tsb on record and recognizes this affects 96-02 gm vehicles with the 4l60e trans(vans, SUV's, rear wheel drive cars and front wheel drive cars with similar transmission). Gm recognizes in their tsb of an ineffective valve body and that this is a "possible" problem and goes on to state it was corrected in late '02 mfg vehicles and there are no "recalls". It provides exact information regarding the above problem (tsb says "customer complaint") gm dealers are charging customers "outrageous" figures for trans replace only for the customer to have the same problem as soon as 10k miles as the new trans is still the "old" model with the defective valve body. Gm further acknowledges that a replacement trans is not necessary(unless "proven" failure) gm further acknowledges the code p1870 in a gm stc class (#17040.01), how to determine the fault even though a simple tsb exists for this. Several tsb's as reference (there are more)#01-07-30-012,020 #99-07-30-005 #77-71-75 #02-07-30-001,030,042. Simply searching the web for p1870 will result in confirmation of said complaint.
